Abstract
The radiometric response function of the High Resolution Spectrograph (HRS) for the Hubble Space Telescope (HST) was measured in 1984. From the system efficiency measurements made in the HRS echelle modes, we have deduced the relative efficiencies ("ripple" functions) of 14 HRS echelle orders. The results agree well with a theoretical model of echelle efficiency, except for a residual shift of apparent blaze angle with spectral order. The discrepancy between nominal and fitted blaze angle decreases with increasing order number.
