Introduction

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.

Tools

APT

The Astronomer's Proposal Tool is used to write, validate, and submit proposals for both HST and JWST.

ETC

The Exposure Time Calculator performs signal-to-noise ratio calculations for all observing modes.

TVT

The Target Visibility Tools help you assess target visibilities before you enter information into APT.

JIST

The JWST Interactive Sensitivity Tool estimates sensitivities and exposure times.

More Tools

WebbPSF

The PSF Simulation Tool simulates point spread functions for JWST instruments.

Mirage

Mirage produces realistic NIRCam and NIRISS simulated data.

MIRISim

Generate simulated MIRI observations using MIRISim.

More Tools

Sensitivities

An overview of the JWST sensitivity and saturation limits is available.

Simulated Data

Simulated data sets help you become familiar with the new JWST instruments.
