Table information for 'gaia_asteroids.gaia_source'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: This service publishes BP/RP reflectance spectra of asteroids from Gaia Data Release 3. Spectra are computed as the ratio between the asteroid flux and an averaged solar analogue flux. Each spectrum consists of 16 spectral points covering wavelengths from approximately 374 nm to 1034 nm. Original data from ESA Gaia Archive: https://gea.esac.esa.int/archive/ (table: gaiadr3.sso_reflectance_spectrum)
