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

    Cartwheel Galaxy observed by JWST using MIRI.

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

  • ETC

    Tarantula Nebula observed by JWST using NIRCam.

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

  • TVT

    First deep field image taken by JWST using NIRCam.

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

More Tools

  • WebbPSF

    Composite image of Cartwheel Galaxy observed by JWST using MIRI and NIRCam.

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

  • JIST

    Composite image of Cosmic Cliffs observed by JWST using MIRI and NIRCam.

    The JWST Interactive Sensitivity Tool estimates sensitivities and exposure times.

  • Sensitivities

    Cosmic Cliffs observed by JWST using NIRCam.

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

More Tools

  • Mirage

    Tarantula Nebula observed by JWST using MIRI

    Mirage produces realistic NIRCam and NIRISS simulated data.

  • MIRISim

    Southern Ring Nebula observed by JWST using NIRCam.

    Generate simulated MIRI observations using MIRISim.

  • Simulated Data

    Composite image of Stephen’s Quintet observed by JWST using MIRI and NIRCam.

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