Scientific paper

The Telescope Image Modeling (TIM) software has been designed to simulate a polychromatic image of a large number of point sources with known colors, as recorded on a pixellated detector after reimaging through an optical system of known charateristics. Though developed primarily for images produced by the Hubble Space Telescope (HST) and its scientific instruments, it is general enough for wider application. The software is modular and produces monochromatic point-spread functions and modulation-transfer functions at intermediate stages. Details of known optical aberrations of the system, microroughness scatter from the telescope mirrors, telescope pupil aberrations, pointing jitter, photon noise and detector defects can all be included.
