| Description: observed_ring_azimuth is an angle measured at a point in the ring plane, starting from the direction of a photon heading to the observer, and ending at the direction of a local radial vector. This angle is projected into the ring plane and measured in the prograde direction. Note that, as seen from the observer, it equals 90 degrees along the right ansa and 270 degrees along the left ansa. Values range from 0 to 360 in units of degrees. Required to be the third field in ring occultation profiles. In labels, the min and max attributes are required. |
