Version History and Change Log

Version 2.3

• Added support for F213 filter
• Allow users to specify psf_cache_location in addCatalogue function.
• Updated WebbPSF version to be >= 1.3
• Constrained numpy version < 2.0 given the conflict with Pandeia.
• Updated documentation to reflect the fact STIPS creates L3 images.

Version 2.2.1

• Fixed a bug on the version of STIPS in __init__.py
• Updated WebbPSF version to be >= 1.1.1 instead of == 1.1.1
• Updated synphot>=1.1.1 and stsynphot>=1.1.0 from forced to specific version.

Version 2.2.0

• Added a functionality to allow for faster simulations of extended sources.
• Fixed a bug related to the simulation of extended sources.
• Fixed a bug related to the WCS.
• Updated pandeia to version 3.1 and its corresponding reference files.
• Changed the minimum required Python version to 3.10

Version 2.1.0

• Updated the Flux PHOTFNU values to match Pandeia
• Updated the background and noise estimates to use Pandeia
• Updated webbpsf to version 1.1
• Updated pandeia to version 2.0

Version 2.0.0

• STIPS now uses an ePSF, and calculates source appearance on a per-source basis
• Dropped support for python 2, and python <= 3.7
• Dropped support for HST and JWST instruments
• Dropped support for jbt background tool, as its results are JWST-specific
• Updated pandeia to 1.7
• Updated webbpsf to 1.0.0
• Dropped astropy helpers code

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 Outdated tests have been removed to allow Travis to pass.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