Spacecraft and Instrument Parameters

(previous releases)

*Note: In order to maintain backward compatibility, there are some empty slots below as expected.

The following parameters refer to the telescope design as specified in Design Cycle 7 or the 2015 WFIRST-AFTA Science Definition Team and WFIRST Study Office Report. Additional Cycle 6 and Cycle 7 reference files are also available. These include the field-of-view layout, slew times, detector properties, distortions, Zernike decompositions of the PSFs, pupil masks, transmission/effective area per filter, and more. Additional Coronagraph Instrument parameters and data are also available.

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 pull-down menu below for the previous versions.) To ensure consistency within the community, these parameters are released here only after approval by the Roman Space Telescope Project Scientist.
