v3.1-IGRINS is a release of the IGRINS PLP for reducing data taken with IGRINS on the McDonald 2.7m, DCT/LDT, and Gemini-South telescopes. For reducing data taken with IGRINS-2 at Gemini-North, use the v3.1-IGRINS-2 release. See the wiki (https://github.com/igrins/plp/wiki) for detailed documentation on how to run the pipeline.

Changes from v3.0.0

  • Updated optimal extraction for stellar recipes. The profile of the trace across the slit used to weight the optimal extraction is now fit column by column instead of calculated for the entire detector. This might correct issues where order edges might not have properly lined up in flux calibrated data. The user can use the old scheme by changing the SLIT_PROFILE_METHOD variable in the run.sh script from column to full. This can also be set by running the individual recipes in the command line with the --slit-profile-method command line argument.
  • Additional filtering added to detect and mask cosmic rays and electronic noise spikes that astroscrappy might have missed.
  • The obsids and frame type nod pattern (e.g. ABBA) are now passed from the recipe_log files to the spec.fits and spec2d.fits file headers with the header keywords OBSIDS and FRMTYPES.
  • Added ability to reduce data with no B frames. This is not considered standard procedure. We usually recommend taking B/OFF exposures, but this feature could be useful for unique science cases or engineering/lab data.
  • Minor tweaks, bug fixes, and python compatibility fixes.
