Spacecraft and Instrument Parameters

The following parameters refer to the telescope design as specified for Phase B. Additional Phase B reference files are available at GSFC. These include the field-of-view layout, detector properties, distortions, Zernike decompositions of the PSFs, pupil masks, transmission/effective area per filter, and more.

These spacecraft/instrument parameters, which are to be used in simulations and in designing science projects, are tied to a regular project design schedule (see the link to parameters in earlier mission phases below). To ensure consistency within the community, these parameters are released here only after approval by the Roman Space Telescope Project Scientist.
