Sorted by DB column index. [Sort alphabetically]
| Name | Table Head | Description | Unit | UCD |
|---|---|---|---|---|
| source_id | Source Id | Unique source identifier. Note that this *cannot* be matched against the DR1 source_id. [Note id] | N/A | meta.id;meta.main |
| ra | RA (ICRS) | Barycentric Right Ascension in ICRS at ref_epoch | deg | pos.eq.ra;meta.main |
| dec | Dec (ICRS) | Barycentric Declination in ICRS at ref_epoch | deg | pos.eq.dec;meta.main |
| ra_error | Err. RA | Standard error of ra (with cos δ applied). | mas | stat.error;pos.eq.ra |
| dec_error | Err. Dec | Standard error of dec | mas | stat.error;pos.eq.dec |
| pmra | µ(RA) | Proper motion in right ascension of the source in ICRS at ref_epoch. This is the projection of the proper motion vector in the direction of increasing right ascension. | mas/yr | pos.pm;pos.eq.ra |
| pmdec | µ(Dec) | Proper motion in declination at ref_epoch. | mas/yr | pos.pm;pos.eq.dec |
| pmra_error | Err. PM(RA) | Standard error of pmra | mas/yr | stat.error;pos.pm;pos.eq.ra |
| pmdec_error | Err. PM(Dec) | Standard error of pmdec | mas/yr | stat.error;pos.pm;pos.eq.dec |
| parallax | Parallax | Absolute barycentric stellar parallax of the source at the reference epoch ref_epoch. If looking for a distance, consider joining with gdr2dist.main and using the distances from there. | mas | pos.parallax |
| parallax_error | Parallax_error | Standard error of parallax | mas | stat.error;pos.parallax |
| phot_g_mean_mag | m_G | Mean magnitude in the G band. This is computed from the G-band mean flux applying the magnitude zero-point in the Vega scale. [Note phot] | mag | phot.mag;em.opt;stat.mean |
| phot_rp_mean_mag | Mag RP | Mean magnitude in the integrated RP band. This is computed from the RP-band mean flux applying the magnitude zero-point in the Vega scale. No error is provided for this quantity as the error distribution is only symmetric in flux space. For errors small compared to the flux (less than 10%, say), the magnitude error is well approximated by 1.09*flux/flux_err. [Note phot] | mag | phot.mag;em.opt.R |
| phot_bp_mean_mag | Mag BP | Mean magnitude in the integrated BP band. This is computed from the BP-band mean flux applying the magnitude zero-point in the Vega scale. No error is provided for this quantity as the error distribution is only symmetric in flux space. For errors small compared to the flux (less than 10%, say), the magnitude error is well approximated by 1.09*flux/flux_err. [Note phot] | mag | phot.mag;em.opt.B |
| roi | Roi | A polygon estimating the area swept over by this star within -5.5 to 50 years | N/A | N/A |
