Mean BP/RP reflectance spectra of Solar System Objects (SSO) (gaiadr3.sso_reflectance_spectrum)

The table has 968288 rows, 10 columns.


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.
