Gaia Synthetic Photometry Catalogue (GSPC)
This is a catalogue of synthetic photometry generated from the Gaia BP/RP mean spectra in Data Release 3 and standardised using wide and reliable sets of external standard stars.
Only sources that have BP/RP mean spectra in Gaia DR3 can be included in this catalogue. Individual magnitudes and fluxes are included only if F/σF>30 in that passband, where F and σF are the flux and its uncertainty.
Synthetic photometry is provided in a selection of photometric systems.
Further details on the generation and composition of the catalogue are available in Gaia Collaboration et al. (2022h).
