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.
Wondering which tool will best meet your needs to simulate Roman Wide Field Instrument (WFI) imaging data? Not sure where to start? This RDox article can help you decide which tool to use!
Would you like to try out a simulation tool without having to install it? The Roman Research Nexus provides a cloud-based scientific computing environment with many Roman tools pre-installed, along with pedagogical notebooks to help you use them. Learn more about the Nexus on RDox.
Check out the Ready, Set, Roman! Training Series for webinar tutorials of Roman simulation tools and more.
-
Roman WFI ETC
The Roman WFI Exposure Time Calculator consists of Pandeia, a Python engine for high-fidelity simulations, the ETC Web Interface, a browser tool that enables sharing with colleagues, and RIST, a simplified version for quick-look purposes.
-
Roman I-Sim
The Roman Image Simulator generates uncalibrated (level 1) and calibrated (level 2) WFI imaging data for all 18 detectors. These products are compatible with the Roman data pipelines.
-
STPSF Simulation
Software for calculating high-fidelity point-spread function (PSF) models for Roman and adapted from JWST for precursor science planning.
-
STIPS
The Space Telescope Imaging Product Simulator generates complex astronomical scenes over a field of view equivalent to a single WFI detector. It uses instrument models and library catalogs for a range of stellar and/or galactic populations.
-
Jupyter Footprint Viewer
The Jupyter Footprint Viewer created by MAST enables viewing telescope footprints on the sky using Aladin. An overview of the Roman capabilities is available on RDox.
