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.

  • Jupyter Footprint Viewer

    The Jupyter notebook Footprint Viewer was created by MAST and is a useful tool for viewing telescope footprints on the sky using Aladin. An overview of the Roman capabilities of the Footprint Viewer is available on RDox.

  • Roman WFI ETC

    The Roman WFI Exposure Time Calculator consists of Pandeia, a Python engine for high-fidelity simulations, the ETC Web Interface, which operates in a browser and enables sharing with colleagues, and RIST, a simplified version for quick-look purposes.

  • WebbPSF Simulation

    Software for calculating high-fidelity point-spread function (PSF) models for Roman and adapted from JWST for precursor science planning.

  • STIPS

    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.
