of the dimensions of an Array object should be displayed and how
they should be displayed in the vertical (line) and horizontal
(sample) dimensions of a display device. This class is a

occultation calibration and geometry supplemental
files.
This class supports occultation data organized
as a time series.

The Uniformly_Sampled_Radius class provides
attributes describing the spectral characteristics of an axis of
an Array object or the rows of a Table object, in cases where
the spectral sampling interval is regular and the sampling
parameters are in wavelength units. The axis is identified
either by using Local_Internal_Reference, or by using axis name.
The latter may be simpler to use if this class applies to
multiple Array objects.

light_source_incidence_angle is an angle
measured from the local surface normal vector to the direction
of a photon arriving from the light source. For rings, the
normal vector is that on the same side of the rings as the light
source, so values always range between 0 and 90 in units of
degrees. The value is always equal to 90 - |
observed_ring_elevation | This will enable users to perform
database searches based on the effective ring opening angle when
they are not concerned about the distinction between north-side
and southside viewpoints. We have included the 'light source'
prefix to the term so that this quantity is not confused with
'incidence angle', a term that is generally associated with
sunlight rather than stars or radio transmitters. Required in
the label if the value is constant for the observation. If the
angle varies for the observation, the min and max attributes are
required in the label. Optional as a field in the data table.

the calculation of the value. Strongly recommended in labels of
ring occultation observations. Not intended as a value for a
table field.

Earth-based observatory. Solar occultations are similar to
stellar occultations except that the Sun is used in place of a
star. Radio occultations typically involve observing the
continuous-wave radio transmissions from a spacecraft as it
passes behind the target as seen from a radio telescope on Earth
or another spacecraft. Required in labels of occultation
observations. Normally not intended as a value for a table
field.

projected_star_diameter provides the projected
angular diameter of the occulted star, from observer to
occulting object.
radial_resolution indicates the nominal radial
distance over which changes in ring properties can be detected
within a data product. Note: this value may be larger than the
radial_sampling_interval value, because a data product can be
over-sampled. Required in labels if the value is fixed, as it is
for stellar occultations. If the value varies, the corresponding
minimum and maximum attributes must be used instead. Not
intended to be used as a table field.
radial_sampling_interval indicates the radial
spacing between consecutive points in a ring profile. In
practice, this may be somewhat smaller than the
radial_resolution because a profile may be over-sampled.
Required in labels if the value is fixed. If the value varies,
the corresponding minimum and and maximum attributes must be
used instead. Not intended to be used as a table field.
reference_time_utc provides a date and time in
UTC format. Given in a label when time values in a table are
given as elapsed seconds offset from a reference time. Unless
there are compelling reasons to do otherwise, reference_time_utc
should correspond to the start of a day. Required anytime a
table field is given relative to a specific date and time other
than when Barycentric Dynamical Time is used (e.g.,
observed_event_tdb).

ring_event_tdb format. Optional in labels; not intended for use
as a table field.
ring_event_start_time_utc gives the UTC time
corresponding to the earliest time given by ring_event_time or
ring_event_tdb in the data table. ring_event_start_time_utc is
required for all ring occultation data.
ring_event_start_time_utc is required label attribute for all
ring occultation data.

required for all ring occultation data. ring_event_stop_time_utc
is required label attribute for all ring occultation data.
ring_intercept_resolution is the size of edge of
a pixel at the distance of the ring intercept point. If the
pixel shape is not square, it is defined by the smaller of the
two edges. Unlike the quantity ‘radial resolution’, these values
are not projected into the ring plane.
ring_longitude specifies the inertial longitude
of a ring feature relative to the prime meridian. In planetary
ring systems, the prime meridian is the ascending node of the
planet's invariable plane on the Earth's mean equator of J2000.
Longitudes are measured in the direction of orbital motion along
the planet's invariable plane to the ring's ascending node, and
thence along the ring plane. Values range from 0 to 360 in units
of degrees. Note: The invariable plane of a planet is equivalent
to its equatorial plane for every ringed planet except Neptune.
Required to be the second field in ring occultation profiles. In
labels, the min and max attributes are required.
ring_longitude_observed_minus_subsolar providees
the difference between the inertial ring longitude of the
observation and inertial ring longitude of the sub-solar point.

parameters such as ring_radius are based. Possible values for
the Saturn ring system are 'Equator', 'A', 'B', 'C', 'D', 'E',
'F', 'G', 'Phoebe'. For the Uranus ring system values are
'Equator', 'six', 'five', 'four', 'alpha', 'beta', 'eta',
'gamma', 'delta', 'lambda','epsilon',nu, mu. An additional
value, 'individual' is also defined. Note that the named rings
of Saturn are in title case while those of Uranus are lower
case, consistent with normal usage by the community. Required in
labels of ring occultation observations.
ring_profile_direction indicates the radial
direction of a ring occultation within a particular data
product. Possible values are 'Ingress', 'Egress', or 'Multiple'.
The value 'Multiple' is used where the occultation track is not
monotonic over relatively short time scales. Generally only used
for some Hubble-based occultations. May be appropriate for
extremely long duration occultations of a high proper motion
star (e.g., u36). Required in labels of ring occultation
observations. Not intended as a value for a table field.
The sampling_base attribute indicates the
numeric base of the associated logarithmic or exponential
sampling interval.
The sampling_interval_length attribute provides
the spacing of points, in units of length, at which data are
sampled and at which a value for an instrument or data parameter
is available. This sampling interval can be either the original
(raw) sampling or the result of some resampling process.
The sampling_scale attribute indicates the type
of scale that applies to the sample interval increments. It must
have a value of either Linear, Logarithmic or Exponential.
sclk_start_time is the value of the spacecraft
clock corresponding to the start_date_time given in the label.

Standard deviation (1-sigma) of projected_sun_diameter in the
observation.
sigma_time_constant indicates the uncertainty in
the time_constant. See Eq. 9 Elliot et al. (1984) Astron. J.
1587-1603. If this attribute is used them the attribute
time_constant also must be present.
spacecraft_event_start_time_utc gives the UTC
time corresponding to the earliest time given by
spacecraft_event_time in the data table. However, while
spacecraft_event_time is given as seconds offset from a
reference time, spacecraft_event_start_time_utc is given as a
UTC date time. Required in the label for radio occultation data.
Not used for stellar occultations.
spacecraft_event_stop_time_utc gives the UTC
time corresponding to the latest time given by
spacecraft_event_time in the data table. However, while
spacecraft_event_time is given as seconds offset from a
reference time, spacecraft_event_stop_time_utc is given as a UTC
date time. Required in the label for radio occultation data. Not
used for stellar occultations.
star_name provides the identifying name of star,
including the catalog name if necessary. Examples include 'sigma
Sgr' and 'SAO 123456' (for star number 123456 in the Smithsonian
Astrophysical Observatory catalog). Use 'Sun' for solar
occultations. Required in labels for stellar and solar
occultations. Not used for radio occultations.
sub_stellar_clock_angle is an angle measured at
a point in the ring plane, from the direction toward a star to
the local radial direction. This angle is projected into the
ring plane and measured in the clockwise (retrograde) direction.
Equivalently, this is the prograde angle from the local radial
direction to the direction toward the star. For stellar
occultation data, this angle is equal to (180 -
OBSERVED_RING_AZIMUTH) mod 360. It is available only for
backward compatibility with previously published Cassini VIMS
occultation data analysis; observed_ring_azimuth is the
preferred quantity for archiving. sub_stellar_clock_angle is an
optional data table field for Cassini VIMS occultation data; not
recommended for other occultation data. In a label, the min and
max variation attributes are optional for Cassini VIMS
occultation data; not recommended for other occultation data.
sub_stellar_ring_azimuth is an angle measured at
a point in the ring plane, starting from the direction of a
photon arriving from a star, and ending at the direction of a
local radial vector. This angle is projected into the ring plane
and measured in the prograde direction. Values range from 0 to
360 in units of degrees. For stellar occultation data, this
angle is equal to (observed_ring_azimuth + 180) mod 360. It is
available only for backward compatibility with previously
published Cassini UVIS occultation data analysis;
observed_ring_azimuth is the preferred quantity for archiving.
sub_stellar_ring_azimuth is an optional data table field for
Cassini UVIS occultation data; not recommended for other
occultation data. In a label, the min and max variation
attributes are optional for Cassini UVIS occultation data; not
recommended for other occultation data.
time_constant indicates the instrumental time
constant of the detector. See Eq. 9 Elliot et al. (1984) Astron.
J. 1587-1603. If this attribute is used them the attribute
time_constant_type also must be present.
time_constant_type distinguishes between three
types of instrumental time constant assumed in a square-well
model. This attribute is required if the time_constant attribute
is present.
time_series_direction indicates the direction
the occultation proceeds through the target within a particular
data product. Possible values are 'Ingress', 'Egress', 'Both' or
'Multiple'. The value 'Multiple' is used where the occultation
track is not monotonic over relatively short time scales.
Generally only used for some Hubble-based occultations. May be
appropriate for extremely long duration occultations of a high
proper motion star (e.g., u36). Not intended as a value for a
table field.
The vertical_display_axis attribute identifies,
by name, the axis of an Array (or Array subclass) that is
intended to be displayed in the vertical or "line" dimension on
a display device. The value of this attribute must match the
value of one, and only one, axis_name attribute in an Axis_Array
class of the associated Array.
The vertical_display_direction attribute
specifies the direction along the screen of a display device
that data along the vertical axis of an Array is supposed to be
displayed.
wavelength of the observation. Optional in
labels. If the observation is over a wavelength range, use the
corresponding minimum and maximum attributes instead.

For rings, the normal vector is that on the same side of the rings as the light source, so values always range between 0 and 90 in units of degrees. The value is always equal to 90 - | observed_ring_elevation | This will enable users to perform database searches based on the effective ring opening angle when they are not concerned about the distinction between north-side and southside viewpoints. We have included the 'light source' prefix to the term so that this quantity is not confused with 'incidence angle', a term that is generally associated with sunlight rather than stars or radio transmitters. Required in the label if the value is constant for the observation. If the angle varies for the observation, the min and max attributes are required in the label.

This angle is positive on the side of the ring plane defined by positive angular momentum, and negative on the opposite side. Values range from -90 to +90 in units of degrees. This angle is constant for stellar occultations, but may vary significantly during radio occultations. Note: The direction of positive angular momentum points toward the IAU-defined north side of the ring plane for Jupiter, Saturn and Neptune, but IAU-defined south side of the ring plane for Uranus. Required in the label if the value is constant for the observation. If the angle varies for the observation, the min and max attributes are required in the label, and observed_ring_elevation is strongly recommended as a field in the data table. The above definition of observed_ring_elevation is equivalent to the most common usage of the term 'ring open angle', B. " ,

"description": "observed_ring_elevation is an angle measured at a point in the ring plane, starting from the ring plane to the direction of a photon heading to the observer. This angle is positive on the side of the ring plane defined by positive angular momentum, and negative on the opposite side. Values range from -90 to +90 in units of degrees. This angle is constant for stellar occultations, but may vary significantly during radio occultations. Note: The direction of positive angular momentum points toward the IAU-defined north side of the ring plane for Jupiter, Saturn and Neptune, but IAU-defined south side of the ring plane for Uranus. Required in the label if the value is constant for the observation. If the angle varies for the observation, the min and max attributes are required in the label, and observed_ring_elevation is strongly recommended as a field in the data table. The above definition of observed_ring_elevation is equivalent to the most common usage of the term 'ring open angle', B. " ,

This refers to the observed occultation track overall, not to the subset that might appear in a particular file (e.g., if an occultation includes both ingress and egress tracks, the value for occultation_direction will be both in the data products for each occultation profile. Permitted values are 'ingress', 'egress', 'both', and 'multiple'. The value 'multiple' is used where the occultation track is not monotonic over relatively short time scales. Generally only used for some Hubble-based occultations. May be appropriate for extremely long duration occultations of a high proper motion star (e.g., u36).

Radio occultations typically involve observing the continuous-wave radio transmissions from a spacecraft as it passes behind the target as seen from a radio telescope on Earth or another spacecraft.

For rings, the normal vector is that on the same side of the rings as the light source, so values always range between 0 and 90 in units of degrees. The value is always equal to 90 - | observed_ring_elevation | This will enable users to perform database searches based on the effective ring opening angle when they are not concerned about the distinction between north-side and southside viewpoints. We have included the 'light source' prefix to the term so that this quantity is not confused with 'incidence angle', a term that is generally associated with sunlight rather than stars or radio transmitters. Required in the label if the value is constant for the observation. If the angle varies for the observation, the min and max attributes are required in the label.

description reference_time_utc provides a date and time in UTC format. Given in a label when time values in a table are given as elapsed seconds offset from a reference time. Unless there are compelling reasons to do otherwise, reference_time_utc should correspond to the start of a day. Required anytime a table field is given relative to a specific date and time other than when Barycentric Dynamical Time is used (e.g., observed_event_tdb).
unit of measure type Units_of_Time
name observed_event_time
version 1.0
value data type ASCII_Real
description observed_event_time indicates the instant at which photons were received at the instrument. As a field in an occultation profile table, it is given in numeric seconds as an offset from the specified UTC reference time. The reference time is preferably the start of a day. In a label the corresponding time interval end point values are given by the required start_date_time_utc and stop_date_time_utc attributes in the Time_Coordinates class. At least one of either observed_event_time or observed_event_tdb, must be a table field for occultation data. Both may be used. observed_event_time is equivalent to spacecraft_event_time for spacecraft data and to earth_received_time for Earth-based data. It is always the photon arrival time, so in this regard we treat typical spacecraft radio occultation data as Earth-based, referring to the time at the DSN receiving station. For an uplink radio occultation, this is the spacecraft event time. Note: For occultation data, PDS prefers year-month-day format for dates rather than year plus day-of-year format. However, either format is permitted.
unit of measure type Units_of_Time
name maximum_observed_event_time
version 1.17
value data type ASCII_Real
description maximum_observed_event_time gives the largest value for observed_event_time in the associated data file. It is given in numeric seconds as an offset from the specified UTC reference time. maximum_observed_event_time is optional in labels since the data file time interval end point values are given by the required start_date_time_utc and stop_date_time_utc attributes in the Time_Coordinates class.
unit of measure type Units_of_Time
name minimum_observed_event_time
version 1.17
value data type ASCII_Real
description minimum_observed_event_time gives the smallest value for observed_event_time in the associated data file. It is given in numeric seconds as an offset from the specified UTC reference time. minimum_observed_event_time is optional in labels since the data file time interval end point values are given by the required start_date_time_utc and stop_date_time_utc attributes in the Time_Coordinates class.
unit of measure type Units_of_Time
name observed_event_tdb
version 1.0
value data type ASCII_Real
description observed_event_tdb indicates the instant at which photons were received at the instrument. It is represented in the 'Barycentric Dynamical Time' system, as a number of elapsed seconds since the J2000 epoch. This is consistent with the definition of 'ephemeris time' as used in the SPICE toolkit. In a label the corresponding values are given by the optional start_observed_event_tdb and stop_observed_event_tdb attributes. At least one of either observed_event_time or observed_event_tdb, must be a table field for occultation data. Both may be used. observed_event_time is equivalent to spacecraft_event_time for spacecraft data and to earth_received_time for Earth-based data. It is always the photon arrival time, so in this regard we treat typical spacecraft radio occultation data as Earth-based, referring to the time at the DSN receiving station. For an uplink radio occultation, this is the spacecraft event time.
unit of measure type Units_of_Time
name observed_event_start_tdb
version 1.17
value data type ASCII_Real
description observed_event_start_tdb indicates the value for earliest time in the described data, and is given in elapsed seconds since the J2000 epoch. Optional in labels; not intended for use as a table field.
unit of measure type Units_of_Time
name observed_event_stop_tdb
version 1.17
value data type ASCII_Real
description observed_event_stop_tdb indicates the value for latest time in the described data, and is given in elapsed seconds since the J2000 epoch. Optional in labels; not intended for use as a table field.
unit of measure type Units_of_Time
name observed_event_time_utc
version 1.0
value data type ASCII_Real
description This attribute is intended to be used as a column in a table. observed_event_time_utc indicates the UTC time corresponding to the instant at which photons were received at the instrument. In a label the corresponding values may be given by the optional start_observed_event_utc and stop_observed_event_utc attributes (or the corresponding values using Barycentric Dynamical Time, _tdb). At least one of either observed_event_time_utc or observed_event_tdb, must be a table field for occultation data. Both may be used. observed_event_time is equivalent to spacecraft_event_time for spacecraft data and to earth_received_time for Earth-based data. It is always the photon arrival time, so in this regard we treat typical spacecraft radio occultation data as Earth-based, referring to the time at the DSN receiving station. For an uplink radio occultation, this is the spacecraft event time.
unit of measure type Units_of_Time

value data type ASCII_Date_Time_YMD_UTC
description observed_event_stop_time_utc indicates the UTC value for latest time in the described data. It is part of a start/stop pair. If one of observed_event_start_time_utc and observed_event_stop_time_utc is used, both must be used.
name spacecraft_event_time
version 1.0
value data type ASCII_Real
description spacecraft_event_time indicates the instant at which an event occurred at the spacecraft, e.g., the arrival or departure of a photon. Required table field for radio occultation data, but not used in stellar occultation data. The time is given in numeric seconds as an offset from the specified UTC reference time. The reference time is preferably the start of a day, and is required to be given in the label using the attribute reference_time_utc. Additionally, in radio occultation labels the corresponding time interval end point values are given by the required start_spacecraft_event_time_utc and stop_spacecraft_event_time_utc attributes.
unit of measure type Units_of_Time
name spacecraft_event_start_time_utc
version 1.17
value data type ASCII_Date_Time_YMD_UTC
description spacecraft_event_start_time_utc gives the UTC time corresponding to the earliest time given by spacecraft_event_time in the data table. However, while spacecraft_event_time is given as seconds offset from a reference time, spacecraft_event_start_time_utc is given as a UTC date time. Required in the label for radio occultation data. Not used for stellar occultations.
unit of measure type Units_of_Time
name spacecraft_event_stop_time_utc
version 1.17

Not used for stellar occultations.
unit of measure type Units_of_Time
name earth_received_time
version 1.0
value data type ASCII_Real
description earth_received_time provides the time at which telemetry or other photons were received on Earth. Intended to be used as a table field which is optional for stellar occultations, and is not used for radio occultation data (one of either observed_event_time or observed_event_tdb is used instead). earth_received_time is given in numeric seconds as an offset from the specified UTC reference time. The reference time is preferably the start of a day, and is required to be given in the label using the attribute reference_time_utc. This is equivalent to OBSERVED_EVENT_TIME for radio occultations. It is an optional table field for stellar occultations and is not used for radio occultations. When earth_received_time is used, the attribute reference_time_utc is required in the label.
unit of measure type Units_of_Time
name earth_received_start_time_utc
version 1.17
value data type ASCII_Date_Time_YMD_UTC
description earth_received_start_time_utc gives the UTC time corresponding to the earliest time for the data product at which telemetry or other photons were received on Earth. Optional for occultation data.

observed_event_time indicates the instant at which photons were received at the
instrument.
As a field in an occultation profile table, it is given in numeric seconds as an offset
from the specified UTC reference time. The reference time is preferably the start of a day.
In a label the corresponding time interval end point values are given by the required
start_date_time_utc and stop_date_time_utc attributes in the Time_Coordinates class.
At least one of either observed_event_time or observed_event_tdb, must be a table field for
occultation data. Both may be used.
observed_event_time is equivalent to spacecraft_event_time for spacecraft data and to
earth_received_time for Earth-based data. It is always the photon arrival time, so in
this regard we treat typical spacecraft radio occultation data as Earth-based, referring
to the time at the DSN receiving station. For an uplink radio occultation, this is the
spacecraft event time.
Note: For occultation data, PDS prefers year-month-day format for dates rather
than year plus day-of-year format. However, either format is permitted.

Clear ring detection but less-reliable ring width and or mid-time due to noise or substantial convolution by star diameter and/or instrumental time constant.
4
Unreliable detection - some hint of a ring occultation, fitted by square-well model, but ~50% chance it is just noise.
5
No detection - Data were recorded at the expected location of a ring occultation, but no ring was observed, either because ring event was obscured by noise or (for the lambda ring) the optical depth of the ring at the observed longitude was below detectability, even if the overall SNR of the data is high.

observed_ring_elevation is an angle measured at a point in the ring plane, starting

positive on the side of the ring plane defined by positive angular momentum, and negative
on the opposite side. Values range from -90 to +90 in units of degrees. This angle is constant
for stellar occultations, but may vary significantly during radio occultations.
Note: The direction of positive angular momentum points toward the IAU-defined north side
of the ring plane for Jupiter, Saturn and Neptune, but IAU-defined south side of the ring
plane for Uranus.

M. Gordon
light_source_incidence_angle is an angle measured from the local surface normal

is that on the same side of the rings as the light source, so values always range between 0
and 90 in units of degrees.
The value is always equal to 90 - | observed_ring_elevation |
This will enable users to perform database searches based on the effective ring opening
angle when they are not concerned about the distinction between north-side and southside
viewpoints.
We have included the 'light source' prefix to the term so that this quantity is not confused
with 'incidence angle', a term that is generally associated with sunlight rather than stars
or radio transmitters.

they should be displayed in the vertical (line) and horizontal
(sample) dimensions of a display device. This class is a modification
of the corresponding class in the Display Dictionary, and
is redefined here for convenience. The local_identifier_reference is
used to identify the array or arrays to which this iteration of the
class applies. Multiple entries are permitted the settings in the
iteration of Display_Direction apply to all of the referenced arrays.

Array object or the rows of a Table object, in cases where the
spectral sampling interval is regular and the sampling
parameters are in wavelength units. The axis is identified
either by using Local_Internal_Reference, or by using axis
name. The latter may be simpler to use if this class applies to
multiple Array objects.
