Roman Software and Simulation Tools
Software and tools for the Nancy Grace Roman Space Telescope are being developed by several partners. This page provides access to tools created and supported by STScI as well as links to the resources provided by partner institutions.
FOV Overlay Tool allows display of the Roman focal plane footprint on sky images from the DSS, SDSS, or GALEX for proposal planning.
Software for calculating high-fidelity point-spread function (PSF) models for Roman and adapted from JWST for precursor science planning.
Multi-mission source simulator and Exposure Time Calculator for JWST and Roman calculate three-dimensional (x, y, lambda) data cubes for astronomical sources and scenes with various spatial and spectral properties.
Software for calculating simulated data for complex astronomical scenes, using instrument models and library catalogs for a range of stellar and/or galactic populations. Adapted from JWST.
