What is the spectral response and dispersion of the GALEX grism mode?
GALEX has a peak spectral response (effective area) of approximately 22 cm2 in the FUV and 49 cm2 in the NUV. The mean response in the FUV between 1350 and 1800 Angstroms is 13 cm2. The mean response in the NUV between 1800 and 2800 Angstroms is 35 cm2. Plots of the response of the most significant spectral orders in each band are shown.
