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.
