WebbPSf is a tool that produces simulated PSFs for the James Webb Space Telescope, NASA's next flagship infrared space telescope. WebbPSF can simulate images for any of the four science instruments plus the fine guidance sensor, including both direct imaging and coronagraphic modes.
Developed by Marshall Perrin at STScI, 2010-2012.

WebbPSF requires a large amount of input data for its simulations, including optical path difference (OPD) maps, filter transmission curves, and coronagraph Lyot mask shapes. These data files are not included in this source distribution available from PYPI. Please see the main WebbPSF web page, linked above, to download the required data tar file.
