Detailed release notes are available at https://webbpsf.readthedocs.io/en/latest/relnotes.html#whatsnew
Briefly, this release includes:
- WFE models for all the JWST instruments, derived from ISIM CV3 measurements at multiple field points as reported in Aronstein et al. (2016) and JWST-RPT-032131
- Various other instrument properties updated based on CV3 and OTIS test measurements, such as focal plane rotations and pupil shears. Information based on JWST-RPT-028027 and JWST-RPT-037134.
- New capability for modeling how focal plane distortions affect PSFs, e.g. by making the projected V2 and V3 axes no longer precisely orthogonal. This is a subtle effect but nonzero. The distortion information is taken from the official SIAF information, specifically in PRDOPSSOC-H-015, and makes use of the new pysiaf package.
- For MIRI in particular, added a model for how PSFs are blurred by photon scattering within the imager detector substrate itself. See MIRI document MIRI-TN-00076-ATC for details on the relevant physics and detector calibration.
- Added new capabilities for interactively modeling mirror moves of the JWST primary segments and secondary mirror.
- All instrument relative spectral response files have been updated to tables derived from the official JWST reference data as used in the Pandeia ETC release 1.2.2.
- The WFIRST WFI optical model has been updated to use optical data from the Cycle 7 design revision for WFI, and the R062 filter was added.
- Various more minor issue fixes, functionality improvements, and API updates for better compliance with the Python PEP8 style guide. See the release notes for full details.
