Spacecraft and Instrument Parameters

The following parameters refer to the telescope design as specified in Design Cycle 6 or the 2015 WFIRST-AFTA Science Definition Team and WFIRST Study Office Report. Additional Cycle 6 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.

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 both the current version and a list of previous ones.) To ensure consistency within the community, these parameters are released here only after approval by the WFIRST Project Scientist.

Recently, all coronagraph parameters were renamed to "CGI_*" from "Coronagraph_*".
