Description

CHANGES

  • Include a fix for when no edges are detected in EdgeTraceSet by adding the bound_detector parameter. Most instruments have a default of bound_detector = False meaning that the code will skip processing any detector where no slit edges are found. Some instuments set the default to be bound_detector = True because the slit edges always or often fall off the edge of the detector (i.e., the detector is fully illuminated). These instruments are currently mmt_mmirs, mmt_bluechannel, not_alfosc, and shane_kast; note that some gemini_gmos data in the DevSuite require bound_detector=True, as well.
  • Improved wavelength template for DEIMOS gratings: 600ZD, 830G.
  • Added new ArI, KrI, NeI, XeI arc lines.
  • PypeIt can now compute arc line FWHM from the lines themselves. This is controlled by a new parset, fwhm_fromlines, which is set to False by default, except for DEIMOS.
  • Added a development document about the DEIMOS wavelength calibration.
  • Limit reduction to detectors 3 and 7 when DEIMOS LVM mask is used (other detectors are empty)
  • Add wavelength RMS to SpecObj. This is an update of the datamodel to 1.3.3
  • Add Bok B&C spectrograph
  • Add pypeit_obslog script that simple compiles and prints metadata from a set of fits files needed by pypeit to run.
  • Change PypeItSetup.from_file_root to require the output path to write the vanilla pypeit file. If no path is provided, the object is instatiated without creating any output.
  • Fixed bug in sensitivity function code adressing issue #747. Revamped sensitivity function completely to compute zeropoints and throughput. Enhanced sensfunc.py QA.
  • Added MOSFIRE QL script.
  • Added support for VLT/SINFONI K 25mas (0.8x0.8 arcsec FOV) platescale
  • Updated docs for differencing imaging sky subtraction.
  • Added "sky" frametype for difference imaging sky subtraction addressing issue # 1068
  • Improved and sped up sensitivity function telluric codes.
  • Fixed bugs in ArchiveReid automatic wavelength identification.
  • Removed numba dependency.
  • Improved pypeit_view_fits script.
  • Fixed ginga bugs in display.py and added automatic cuts to show_2dspec
  • Added latin hypercube sampler to pypeit.utils which is required for differential evolution optimizations.
  • Improved GMOS R400 wavelength solution
  • Turned off GMOS-S binning restriction
  • Add GTC OSIRIS spectrograph
  • Updates for docs on adding new spectrographs. And a bok test
  • Added a new pypeit_collate_1d tool to automatically group 1D Spectra from multiple files by group and coadd them.
  • PypeIt will now add HISTORY keyword entries to FITS files.
  • use_maskdesign is turned off for DEIMOS LVM masks
  • a new parameter use_user_fwhm is added in ExtractionPar to allow the user to set their preferred fwhm
  • Improved slittrace.assign_maskinfo
  • PypeIt can now force extractions of DEIMOS non detected objects at the location expected from slitmask design.
  • SpecObj and SlitTrace datamodel versions updated
  • pypeit_show_2dspec shows traces of forced extraction and manual extraction with a different colors
  • Updated docs about extraction and DEIMOS
