Asteroid identification.
Designation:UTF8_String::none:The asteroid number. For planetary satellites, PxxMyy, where xx is the planet number, and mm is the satellite in that system.
Name:UTF8_String::none:Asteroid's name, or other identification.
SatName:UTF8_String::none:Satellite's IAU name, or other identification.
Obs_Date:ASCII_Date_YMD::none:Date of the observation.

Satellite details
CBET:UTF8_string::none:If this is the occultation discovery observation, the CBET number announcing the discovery
Sep:UTF8_string::mas:The observed separation of the satellite
PA:UTF8_string::deg:The observed position angle of the satellite
SatMaj:UTF8_string::km:The observed major axis of the satellite
SatMin:UTF8_string::km:The observed minor axis of the satellite
SatAxisPA:UTF8_string::deg:The PA of the major axis of the satellite
Fit_Quality:UTF8_string::none:The quality of the fit to the observation. ~ None. No fit to the satellite. This is only used when the observations indicate the detection of a satellite, but the observations have not been analyzed to obtain a fit to the observations. ~ Is it a satellite? The observations indicates the possibility of a satellite. However the observational evidence is not sufficient to assert a definite detection. [Single-chord visual observations would typically fall into this category, as well as single noisy video recordings] ~ Approx offset. The existence of a satellite is reasonably definite. The approximate location of the satellite can be determined, but not its size or shape  ~ Offset + size. An accurate location location of the satellite is determined, together with a size derived by assuming it is spherical ~ Offset + shape. An accurate determination of the location, size and shape of the satellite.
