13.6.2 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):
-
•
pseudocolour (was astrometric_pseudo_colour);
-
•
pseudocolour_error (was astrometric_pseudo_colour_error);
-
•
astrometric_matched_transits (was astrometric_matched_observations);
-
•
matched_transits (was matched_observations);
-
•
dr2_radial_velocity (was radial_velocity – see Section 6.1.1);
-
•
dr2_radial_velocity_error (was radial_velocity_error – see Section 6.1.1);
-
•
dr2_rv_nb_transits (was rv_nb_transits – see Section 6.1.1);
-
•
dr2_rv_template_teff (was rv_template_teff – see Section 6.1.1);
-
•
dr2_rv_template_logg (was rv_template_logg – see Section 6.1.1);
-
•
dr2_rv_template_fe_h (was rv_template_fe_h – see Section 6.1.1).
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.
