Short summary
We propose to parameterize the instrumental spectral response function (ISRF) as a "super-Gaussian", which can reproduce a variety of shapes, from point-hat to boxcar shape, by just adding one parameter to the "classical" Gaussian. In addition, the super-Gaussian allows for a straightforward parametrization of the effect of ISRF changes.
