This release improves a subset of WFIRST functionality to add WFI's Prism and Grism modes using cycle 8 models for wavefront error.

This release only improves a subset of WFIRST functionality; additional improvements to both WFIRST (including renaming to Roman) and JWST models will be at the upcoming 1.0.0 major release.

WFIRST Improvements

  • New Grism and Prism filters: [:pr:416, :pr:471, :user:robelgeda]
    • GRISM_FILTER = 'G150'
    • PRISM_FILTER = 'P120'
  • Changing filters to G150 or P120 changes the mode of the WFI and the aberrations files (unless there is a user aberrations override) [:pr:416, :pr:471, :user:robelgeda]
  • New WFI.mode: Class property that returns the current mode of the WFI instance by passing the current filter to WFI. _get_filter_mode. WFI modes are: [:pr:416, :pr:471, :user:robelgeda]
    • Imaging
    • Grism
    • Prisim
  • New WFI.override_aberrations(aberrations_path): Overrides and locks the current aberrations with aberrations at aberrations_path. Lock means changing the filter/mode has no effect on the aberrations. [:pr:416, :pr:471, :user:robelgeda]
  • New WFI.reset_override_aberrations(): Releases WFI.override_aberrations lock and start using the default aberrations. [:pr:416, :pr:471, :user:robelgeda]
  • New Tests for mode and filter switching. [:pr:416, :pr:471, :user:robelgeda]
  • New Field point nearest point approximation (extrapolation). [:pr:416, :pr:471, :user:robelgeda]

Software and Package Infrastructure Updates:

  • This release uses Github Actions CI and removes TravisCI. [:pr:455, :user:shanosborne, :pr:471, :user:robelgeda]
