JWST Observer Offers a New Way To Explore JWST Sensitivities

Have you ever wanted to quickly estimate the feasibility of a new JWST proposal, but did not have the time to craft an ETC calculation? There is now a new quick-look sensitivity tool available for JWST. The JWST Interactive Sensitivity Tool (JIST) uses a pre-calculated grid of ETC calculations to quickly estimate sensitivites and exposure times in a responsive, interactive plot, and indicates when your observation might saturate. All you have to worry about is the brightness of your target. 

Of course, once you have used JIST to make your initial estimates, you should head over to the JWST ETC to help craft your detailed observations.

Learn more about JIST on JDox.
