      abstract     = {Spectroradiometric calibration aims to determine the
                      instrumental spectral response function (ISRF) parameters
                      and radiometric coefficients of an instrument’s spectral
                      bands across all spatial pixels. Typically, this is done by
                      making separate spectral and radiometric calibration
                      measurements. We present a method for the simultaneous
                      traceable spectroradiometric calibration of an imaging
                      spectrometer, using the Spectroscopically Tunable Absolute

                      Ground Support Equipment (STAR-cc-OGSE) facility. We
                      performed the forward simulation of calibration data
                      acquisition by convolving input spectra with the sensor
                      model’s response and simulated a slit scattering function
                      (SSF)-based calibration, allowing for both ISRF coefficients
                      and the absolute spectral responsivities to be accurately
                      retrieved from a single series of measurements. We show how
                      the SSF method minimizes uncertainties compared to the
                      traditional spectroradiometric calibration approach.},
