Description

Major Changes
  • Reduction of Keck/DEIMOS now defaults to mosaics of red and blue detector pairs
  • Package data is no longer distributed via PyPI. Instead, we use astropy's downloading/caching system as needed by the user
  • Significant refactor of object finding and 2D extraction algorithms
  • Added support for:
    • VLT FORS2 600z grism
    • VLT XShooter UVB arm
Minor Changes/Improvements
  • Default comb_id ordering matches the sorted file name in pypeit_setup
  • Save output wavelength calibration from pypeit_identify to the cache for direct reuse in data reduction.
  • The pypeit_identify GUI can now toggle between linear and log scaling of the arc spectrum flux.
  • Dark subtraction now ignores any difference in exposure time, by default
  • Added more flexible quicklook that can handle dithering.
  • Bug fixes in local sky subtraction and extraction
  • Fixed pypeit_setup issues due to bad LRIS headers.
  • Fixed a bug in 2d coadding when objects were not being identified.
  • Refactored 2d extraction.
  • Minor enhancements to pypeit_identify GUI
  • Refactoring of pypeit_show_wvcalib GUI
Instrument-specific Changes/Improvements
  • Improve Keck/KCWI automatic frame typing.
  • Added wavelength templates for
    • Keck/MOSFIRE (OH and arc lines)
    • bok_bc 300 grating template
  • Improved wavelength solution for Gemini-Nort E2V detector
  • Keck/DEIMOS now uses gain/RN values measured periodically by WMKO
  • Added enhancements and fixes for Keck lris red Mark4.
  • Added code to better parse Gemini/GNIRS dither sequences
