Permissible Value(s)ValueValue Meaning
 0Not observable - observations at the predicted occultation event time for this ring were either not recorded (for example, the star was below the horizon) or the occultation chord did not intersect the ring.
 1High-SNR profile with sharp edges matched by square-well model fit.
 2Moderate-SNR profile with well-defined midtime from square-well model fit but possible systematic deviations of observed ring profile from model fit.
 3Clear 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.
 4Unreliable detection - some hint of a ring occultation, fitted by square-well model, but ~50% chance it is just noise.
 5No 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.
 6Is not an indication of data quality. Indicates the product is a profile of the entire ring system based on the equator system of the planet.
 BBackground is from a different occultation.
 FSignificant fraction of Sun is outside FOV.
 RSome of the data are flagged for removal.
 UUnocculted solar signal is from a different occultation.
 XObservation is unusable for analysis.
