This table contains the mean BP/RP reflectance spectra of asteroids computed as the ratio between the asteroid flux and an averaged solar analogue flux. In each row, the reflectance spectrum of a given asteroid is given at a given wavelength. Entries for all asteroids are concatenated into a single table.
A unique single numerical identifier of the source. Note in particular that these identifiers are by convention negative for SSOs.
All Gaia data processed by the Data Processing and Analysis Consortium comes tagged with a solution identifier. This is a numeric field attached to each table row that can be used to unequivocally identify the version of all the subsystems that were used in the generation of the data as well as the input data used. It is mainly for internal DPAC use but is included in the published data releases to enable end users to examine the provenance of processed data products. To decode a given solution ID visit https://gaia.esac.esa.int/decoder/solnDecoder.jsp.
Minor planet number attributed by the Minor Planet Centre (MPC). It is set to zero for the natural planetary satellites and the candidate new minor planets.
Name of the object. It follows the Minor Planet Centre convention for the minor planets. For bundle of observations that are not identified at the time of the data processing, the name is a string like Gaia-DR3SSO-RN where RN is a running number unique to the bundle. For the natural satellites of the major planets, its standard name is given followed by a string (XYY) where X is the first letter of the planetary system it belongs to, and YY is the number of the satellite in Roman numeral.
Number of wavelength bins in the reflectance spectrum.
Number of epoch spectra combined to generated the mean reflectance spectrum.
Reflectance value at the given wavelength.
Error in the reflectance.
This flag indicates the quality of the reflectance in the applicable wavelength channel, and can take the following values:
0: Good quality
1: Potential poor quality
2: The quality appears compromised. The use of this reflectance value is not recommended.
