VizieR Online Data Catalog: Gaia Early Data Release 3 photometric passbands (Riello+, 2021)

These tabular data describes the photometric system defined by the G, G_BP and G_RP Gaia bands for Gaia Early Data Release 3.

The tables provide the full passband and the corresponding zero point for each of the photometric bands. The zero points are available both in the VEGAMAG and AB systems.

The passband calibration is based on the modelling of a set of corrections applied to pre-launch knowledge of the instrument, to find the best match between observed and synthetic photometry for a set of calibrators. For EDR3 a large set of calibrators covering a wide range of spectra types was used for the passband calibration.

For these sources reconstructed SEDs were obtained from externally calibrated Gaia BP/RP spectra.
