STIPS Version 2.1.0

This release focuses on updates to the background and flux estimates used in STIPS, as well as updates to the documentation and some bug fixes.

What's Changed

• Updated the PHOTFNU flux zeropoints used to calculate fluxes to match those in Pandeia.
• Fixed a bug that was causing the background noise to be too high.
• Modified the background estimates to use Pandeia.
• Updated the dependencies to the latest version, most notably Pandeia 3.0 and WebbPSF 1.1
• Updated Jupyter Notebook with more detailed instructions and cleared their outputs.
• Updated the way the central offset is calculated so that it uses the SOC Roman tools SIAF

Full Changelog: v1.0.8...v2.0.0

Bugfix Release

Fixes systematic errors in source position on-detector.

Version 1.0.8

2020 May 22

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 Outdated tests have been removed to allow Travis to pass.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]

Version 1.0.7

2020 January 8

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]
