VOResource XML (that's something exclusively for VO nerds)
The Flag_Gaia is computed by cross-matching the catalogue with the Gaia catalogue:
| Value | Meaning |
| 1 | The object if possibly a Gaia object: the nearest Gaia source is between 1.5 arcsec and 2 arcsec. |
| 2 | The object if probably a Gaia object: the nearest Gaia source is between 0.6 arcsec and 1.5 arcsec. |
| 3 | The object is definitely a Gaia object: the nearest Gaia source is nearer than 0.6 arcsec. |
| 0 | Otherwise (the nearest Gaia source is farer than 2 arcsec). |
The Flag_OptNIR_Obs and Flag_OptNIR_Det are computed while cross-matching the optical and near/mid infrared catalogues and indicate if a source was observed (i.e. is on the coverage of surveys at the given regime) or detected (i.e. is present in the catalogue) in various wavelength regime. The detection is based on the detection wavelengths of the catalogues, and to be counted as detected, a source must be present in at least two catalogues.
The flag is a composed binary flag with these values:
| Value | Meaning |
| 1 | Observation/detection in optical wavelengths. |
| 2 | Observation/detection in near-infrared wavelengths. |
| 4 | Observation/detection in mid-infrared wavelengths. |
