Image and Spectroscopy Simulator

The Space Telescope Image Product Simulator (STIPS) is a tool designed to help the astronomical community prepare for JWST observations. 

NOTE: In order to access STIPS JWST, you will need an STScI SSO Account.

Introduction to STIPS for JWST

The STIPS (Space Telescope Image Product Simulator) software produces simulated imaging data for complex wide-area astronomical scenes, based on:

  • User inputs
  • Instrument models
  • Library catalogues for a range of stellar and/or galactic populations.

It was originally developed for the JWST mission, but now has been extended to include WFIRST functionality as well.

The current JWST version produces images covering the MIRI detector, either one or both NIRCam Long detectors, and either one, four, or all eight NIRCam Short detectors. STIPS uses PSF models generated by WebbPSF and uses instrument throughputs calculated by Pandeia/JWST ETC.

STIPS is based on a Python module and a web interface that provides a straightforward way of creating observation simulations. In its current implementation, it runs server-side and allows users to submit simulations and view/retrieve the results.
