Orbital fit residuals (gaiadr2.aux_sso_orbit_residuals)
The table has 1977702 rows, 10 columns.
Description
Residuals with respect to an orbital fit considering only the Gaia observations. Each entry has a corresponding record in the table sso_observation. A flag is given, indicating if the observation has been rejected by the fit procedure.
