Ghroth

We implement a number of changes to fix bugs and small changes to both the main IDLspec2d pipeline and the SOS mountain pipeline

• Update spplan2d
  - to utilize twilight flats (if no field-mjd matched flats are available)
  - allow skip of commission fields
  - allow test exposures with field = -999 to run with fieldid=0
• Addition of a prototype spAll-lite file
• Addition of spectrophotometric QA plots on a field-mjd basis
• Fixed a bug in Extinction values from dust3d model
  - The addition of columns identifying utilized extinction source (EBV_TYPE)
  - Updated SFD_EBV column name in spall (and other steps) to EBV
• Corrected bug in loadSN2Value to allow updates of SN2 values
• Updated APO red CCD gain values to SDSS-V updated CCD
  - modified sdssproc to read these from a new opGain.par file to clean up and allow for easier future updates
• Added LCO arc lamp line file (lampHeNe.dat) and included an option to use in fitarcimage.pro
• modified SN2 and fieldquality color/values to be consistent
  - both in fieldlist and spall
  - scales SN2 of fields with < 3600s exposure to 3600s before comparing with reference values of SN2_b <10 and SN2_r<22
• Updated Fieldlist
  - added fieldcadence (after retrieving from targetdb via run_plugmap_supplements)
• Updated spAll
  - RACAT, DECCAT, MJD_FINAL are reported as double
  - additional decimal point included in RA/DEC_LIST
  - sfd_ebv → ebv
  - added ebv_type
  - added cadence
  - Implemented an option to skip the step to build specprimary and nspecobs columns (but still allow as post step)
  - optimized the code to produce specprimary, nspecobs, etc.
  - added FIBER_RA, FIBER_DEC, and specobjid (required for sas_mwm_healpix)
  - specobjid is actually reproduced in this step (to ensure consistency
  - copying them from the specreduce1d step outputs was producing inconsistent values due to data types)
• Utilizing astrometry values from target_db instead of crossmatching to Gaia for retrieval
• modified read_sos.py to get parent confSummary files (for dithered fields) if it is not included in the fibermap fits file
• Cleaned up fibermap/spall columns
  - replacing -999. with NANs
• fixed bug with utilizing fibermask for calibrations, when more than 1 calibration frame of type is included in the plan

Bast

We implement a modification to the daily target level coadd algorithm. This modification splits the coadd into a two-stage process, with the first stage combining the blue and red camera (including outlier rejection), and the second stage combining the (already red+blue combined) exposures (without outlier rejection). This strategy was implemented to improve the coadds of exposures with significant flux differences seen in the SDSS-V FPS era. EXP_DISP_MED was added to SpAll to characterize the flux dispersion between the exposures. All exposures are included as extensions in the full versions of the spec files for custom post-pipeline coadds. Additional columns of lists of exposure level metadata are included in the SpAll file for reference. The reading of the confSummary files was replaced with the confSummaryF files to incorporate the more accurate fiber positions (as measured by the FVC loop). Additionally, several other bug fixes were incorporated into the main IDLspec2d and SOS pipelines.

Hypnos

We implement several bug fixes to the flux calibration and flat fielding of the reduced spectra. We also implement improvements to the final spectral metadata included in the spec-field-mjd-catalogid.fits file headers and the spAll extensions and file. These improvements included propagating some information on a per-target rather than per-field basis since we coadd on a target level. We switch from coadding via an RA-DEC match to a coadd based on catalogid. We also switched off the interpolated flux calibration vectors for all fields with less than 60 standards (in practice only leaving this on for BHM-RM fields).
