Software Tools To Help with Proposals
We provide you with a variety of tools to help you investigate options for viability and, ultimately, assist in the generation of a proposal for submission to the JWST Time Allocation process. We also offer a handy Pocket Guide that provides technical information about each instrument.
The Astronomer's Proposal Tool is used to write, validate, and submit proposals for both HST and JWST.
The Exposure Time Calculator performs signal-to-noise ratio calculations for all observing modes.
The Target Visibility Tools help you assess target visibilities before you enter information into APT.
The JWST Interactive Sensitivity Tool estimates sensitivities and exposure times.
An overview of the JWST sensitivity and saturation limits is available.
Simulated data sets help you become familiar with the new JWST instruments.
