eROSITA PSF at 1.5 keV for different off-axis angles from PANTER measurements (Burwitz et al. 2014). The on-axis PSF has a full width at half maximum (FWHM) of 16 arcsec, which deteriorates for larger off-axis angles leading to an average survey PSF of 25−30 arcsec The images are in linear scaling, and are upscaled and smoothly interpolated from the measured data by a factor of three.
