Filter Description

Filter ID (?) :GAIA/GAIA2.Grp
Description (?) :GAIA Grp filter, DR2
Phot.System (?) :GAIA
Detector Type (?) :Energy counter
Band Name (?) :------
Obs. Facility (?) :GAIA
Instrument (?) :GAIA
Comments (?) :Original passband used for the magnitudes published in Gaia DR2.

The original curve has been multiplied by λ and normalized to maximum transmission=1 (to transform it to "energy counting" curve)
