JWST Other Tools

There are a number of different software tools available to assist JWST users as they investigate various proposal options for viability, and ultimately generate a proposal for submission the the JWST time allocation process. This article provides a quick look overview of what is available.

The primary JWST tools needed to support proposal writing include the JWST Exposure Time Calculator and the Astronomer's Proposal Tool.  However, the JWST project supports a number of other specialized tools that can be great time-savers for those investigating special cases.  These tools typically are used to provide a quick look into parameters such as visibility, sensitivity, or variations in background levels as a function of time.

Tools for simulating JWST performance

External tools of interest to proposers

The following tool has been developed by external community members and is not supported directly by STScI. However, many in the broader community may find it useful and a link is provided for visibility and convenience.   

  • MIRISIM can generate imaging, as well as low- and medium-resolution spectroscopic data simulations for MIRI. These simulated observations can help proposers better understand the capabilities of the instrument, prepare their own observations, and plan ahead for data analysis. MIRISIM was developed and is supported by the MIRI consortium.

Help for this tool is not available through the JWST Help Desk since the tool is managed outside of STScI.
