STPSF

STPSF produces simulated PSFs for the James Webb Space Telescope, NASA's flagship infrared space telescope. STPSF can simulate images for any of the four science instruments plus the fine guidance sensor, including both direct imaging, coronagraphic, and spectroscopic modes. STPSF also supports simulating PSFs for the upcoming Nancy Grace Roman Space Telescope (formerly WFIRST), including its Wide Field Instrument and a preliminary version of the Coronagraph Instrument.
