Pre-launch Transmission profiles of all instruments


    The normalised G/BP/RP/RVS passbands, expressed as response to photons, i.e., as quantum efficiency, can be downloaded here. These data are pre-launch predictions and do not apply to Gaia DR2 and later releases. For Gaia DR2 passbands, please go here. For Gaia (E)DR3 passbands, please go here.
