This release adds support for the WFI's F213 filter, updates constants for pivot wavelengths and mirror area, and upgrades minimum required versions of Pandeia (2024.12-roman) and STPSF (v2.0.0, now under this name instead of WebbPSF). It updates the detector naming scheme from SCANN to WFINN for compatibility with other Roman SOC simulation tools.

Version 2.3.0 of STIPS fixes bugs related to reading Internal tables and allowing users to specify a custom psf_cache_location. We have also added citation resources on GitHub and Zenodo.

The STIPS reference data have also received their first update in a few years and are available for download on Box. Now at version 1.0.10, the reference files feature a recalculated Phoenix grid that now incorporates the F213 filter.

STIPS Improvements

• PSFs generated with webbpsf are now PSF grids. [:pr:``, :user:york-stsci]
• STIPS has the option to keep all data in memory. [:pr:``, :user:york-stsci]
• Data files have been removed from the repo to allow STIPS to be uploaded to PyPi (pip). The data has been migrated to a STScI box folder. Users can now download the data and set their stips_data to allow access to the data that once lived in the repository. [:pr:59, :user:york-stsci]
• Travis was setup to run and pass tests. Outdated tests have been removed to allow Travis to pass. [:pr:65, :user:robelgeda]
• Test data has been moved to a STScI box folder. [:pr:64, :user:robelgeda]
• dev folder added for any developer related tools. [:pr:69, :user:robelgeda]
• Frozen environments saved at dev/conda_envs. [:pr:69, :user:robelgeda]

STIPS Improvements

• Cookie cutter template used to create better package infrastructure. [:pr:40, :user:robelgeda]
• Docker file added for ease of install. [:pr:48, :user:robelgeda]
• environment.yml added for easy conda env build. [:pr:42, :user:robelgeda]
• Read the Docs documentation established. [:pr:55, :user:robelgeda]
• F062 filter added to WFIRST WFI. [:pr:51, :user:york-stsci]
• Update STIPS to use WbbPSF 0.9.0. [:pr:51, :user:york-stsci]
• Travis CI initiated for unit and regression testing. [:pr:40, :user:robelgeda]
• Python version set to 3.7 [:pr:40, :user:robelgeda]
• Licenses updated [:pr:40, :user:robelgeda]

General bug fixes and small changes

• Updated astro_image.py to use a PC matrix rather than a CD matrix for the image WCS, which hopefully will result in astropy actually giving you a correctly formatted FITS WCS. [:pr:46, :user:york-stsci]
• Adding WCS information to PSF files. PSF files will now have the following:
  • RA equal to the observation RA at which they were produced
  • DEC equal to the observation DEC at which they were produced
  • PA equal to the observation PA at which they were produced
  • CDELT keywords equal to the PIXELSCL keyword, but adjusted to degrees rather than arcsec.
  • [:pr:47, :user:york-stsci]
