SSO Observation (gaiadr2.sso_observation)
The table has 1977702 rows, 27 columns.
Description
Solar System object observations. Each table line contained 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.
