Abstract
In this contribution, we investigate to which degree strayligh influences results from the GREGOR Infrared Spectrograph. To this end, we use the synthesis module of the SIR code to perform radiative transfer calculations in a 3D-MHD model atmosphere of a full sunspot. We convolve the resulting Stokes spectra spatially and spectrally with theoretical point spread functions (PSF) as well as a PSF obtained during the Mercury transit and compare the results to GRIS observations.
