Solar System Object observations (gaiadr3.sso_observation)
The table has 23336467 rows, 36 columns.
Description
Solar System object observations. Each table line contains data obtained during the transit of the source on a single CCD, during a single transit. The corresponding epoch is provided. Data not varying within the transit are repeated identically for all single observations of that transit.
Known issues
The number of observations (num_of_obs) in the sso_source table contains a wrong value in 4 cases, with the correct number being present in the sso_observation table:
- sourceId -4284051496, corresponding to number_mp (91580), has 317 num_of_obs in the sso_source table, but 310 entries in the sso_observation table;
- sourceId -4283766166, corresponding to number_mp (120113), has 74 num_of_obs in the sso_source table, but 69 entries in the sso_observation table;
- sourceId -4281797236, corresponding to number_mp (317006), has 64 num_of_obs in the sso_source table, but 63 entries in the sso_observation table;
- sourceId -4283795346, corresponding to number_mp (117195), has 76 num_of_obs in the sso_source table, but 75 entries in the sso_observation_table.
