WebbPSF produces simulated PSFs for the James Webb Space Telescope, NASA's
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.

WebbPSF 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.

Developed by Marshall Perrin, Joseph Long, Neil Zimmerman, Robel Geda, Shannon
Osborne, Marcio Melendez Hernandez, Lauren Chambers, Keira Brooks, Charles-Phillipe Lajoie, Jarron Leisenring, Alden Jurling, and collaborators, 2010-2020.

Documentation can be found online at https://webbpsf.readthedocs.io

WebbPSF requires 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.
Please see the documentation to download the required data files.

In particular, the 2012 SPIE paper gives a broad overview, the 2014 SPIE paper presents comparisons to instrument
cryotest data, and the Technical Report document describes in more detail the relevant optical physics, explains design
decisions and motivation for WebbPSF’s architecture, and presents extensive validation tests demonstrating consistency
between WebbPSF and other PSF simulation packages used throughout the JWST project.
