Physically, the result is that some photo-electron signals are measured in different pixels than the incident photon hit, acting to blur PSFs slightly. STPSF was originally designed as an optics-only simulation, leaving it up to users to optionally use other codes to model detector non-ideal behaviors. \n", "\n", "
