      Description

      Jared Siegel reports a significant degradation in sky subtraction performance following updating from CALIB-2023-07-v4 to CALIB-2023-07-v5. The update only involved fixing the validity ranges for the fiberProfiles, so all arms should now be using the (correct) July fiberProfiles to reduce his exposure except n3 (which didn't have fiberProfiles for April 2023).

      Jared's reduction script:

      . /scratch/gpfs/HSC/PFS/stack/current/loadLSST.bash
      
      setup pfs_pipe2d w.2023.37
      
      reduceExposure.py /projects/HSC/PFS/Subaru --calib=/projects/HSC/PFS/Subaru/CALIB --rerun=siegeljc/10 -j 8 --id visit=97252 -c isr.doFlat=False
      
      <Fiber reassignment, to set N% to sky fibers>
      
      reduceExposure.py /projects/HSC/PFS/Subaru --calib=/projects/HSC/PFS/Subaru/CALIB --rerun=siegeljc/10 -j 8 --id visit=97252 -c isr.doFlat=False
      
      mergeArms.py /projects/HSC/PFS/Subaru --calib=/projects/HSC/PFS/Subaru/CALIB --rerun=siegeljc/10 -j 8 --id visit=97252
