The MAST FOV Overlay Tool is a web-service in the Barbara A. Mikulski Archive for Space Telescopes (MAST) that allows display of the WFIRST focal plane footprint on sky images from the DSS, SDSS, or GALEX. The tool also allows retrieval of catalog objects (e.g., GSC2, 2MASS, WISE) within specified detectors. It should be useful for various studies and observation planning, and allows users to become familiar with the WFIRST capabilities to perform surveys of wide fields.

The WebbPSF-WFIRST software calculates high-fidelity point-spread function (PSF) models. It was originally developed for JWST, but has been extended to include WFIRST functionality. This provides PSFs for use in other tools and for precursor science planning.

The Pandeia software calculates three-dimensional (x, y, lambda) data cubes for astronomical sources and scenes (galactic or extragalactic) with a choice of spatial and spectral properties. It was developed for JWST, but has been extended to include WFIRST functionality. The data cubes are processed through instrument models to generate simulated data, enabling for example accurate signal-to-noise ratio and exposure time calculations.

The STIPS software (Space Telescope Image Product Simulator) allows calculation of simulated data for complex astronomical scenes, using instrument models and library catalogs for a range of stellar and/or galactic populations. It is under development for JWST, but has been extended to include WFIRST functionality. STIPS can be used for creation of complex star fields with specified clustering, age, metallicity, IMF, and other properties.
