JWST Interactive Sensitivity Tool
JIST uses a pre-calculated grid of ETC calculations to quickly estimate sensitivities and exposure times in a responsive, interactive plot, and indicates when your observation might saturate.
JIST offers a restricted view of the full JWST ETC parameter space, and assumes:
- A single flat-spectrum (in Fnu) point source.
- A single standard background spectrum corresponding to 1.2 times the minimum zodiacal background.
- ETC defaults for all other parameters.
Finally, most, but not all, science modes are available in JIST.
After using JIST to make your initial estimates, you are invited to use the JWST ETC to craft your proposal.
