12.6 Differences between the Gaia EDR3 and DR2 data models

12.6.2 Column changes in Gaia EDR3

Where tables are common between Gaia EDR3 and DR2, the following deletions and renamings should be noted (we do not include columns that are new in Gaia EDR3 in this digest):

Main catalogue tables

The following columns have been deleted from table gaia_source:

  • astrometric_weight_al;

  • mean_varpi_factor_al;

  • frame_rotator_object_type;

  • phot_variable_flag;

  • priam_flags;

  • teff_val;

  • teff_percentile_lower;

  • teff_percentile_upper;

  • a_g_val;

  • a_g_percentile_lower;

  • a_g_percentile_upper;

  • e_bp_min_rp_val;

  • e_bp_min_rp_percentile_upper;

  • e_bp_min_rp_percentile_lower;

  • flame_flags

  • radius_val;

  • radius_percentile_upper;

  • radius_percentile_lower;

  • lum_val;

  • lum_percentile_upper;

  • lum_percentile_lower.

Note that variability information (including phot_variable_flag) and all the subsequent astrophysical parameters itemised above will reappear, much expanded, in Gaia DR3.

The following columns have been renamed in table gaia_source (old Gaia DR2 names in parentheses):

The following column remains in table gaia_source with the same name but the definition/derivation has changed (see the linked descriptions for more detail):

Crossmatches

The following columns have been deleted in _best_neighbour tables:

  • gaia_astrometric_params;

  • best_neighbour_multiplicity.

The following column has been deleted in _neighbourhood tables:

  • gaia_astrometric_params.
