This page provides links to the current JMS default input files and the pre-computed sample reports generated by the various JMS tools.

Sample reports are available only from tools which utilize the Design Reference Mission (DRM) data. Other tools require the user to enter single exposure observation data.

There are now two Spacecraft/Telescope Architecture (ARCH) files, which differ only in the predictive spacecraft ephemeris being used. The "nominal" ARCH file uses the nominal 15-year JWST ephemeris, while the "alternate" ARCH file uses a 10-year ephemeris that models a "worst-case" stray-light scenario.

One additional item of interest is the COBE/DIRBE spectral radiance map file.
