  • fastspec-main-dark-25895-39627685651024930- [SIII] is dropped

I looked at this object in iron and [SIII] 9532 gets dropped not because of a bug but because it's too close to the edge of the spectral range. In the main branch, the redshifted line-center can't be within 5 Angstrom of either edge of the spectrum, which is perhaps too conservative. Here's the fit with a 0-Angstrom padding (which isn't great, but at least the line doesn't get dropped...)

For the record, here's what I ran:

source /global/cfs/cdirs/desi/software/desi_environment.sh main
module load fastspecfit/main

fastspec /global/cfs/cdirs/desi/spectro/redux/guadalupe/healpix/main/dark/258/25895/redrock-main-dark-25895.fits \
  --targetids 39627685651024930 -o fastspec.fits --verbose
fastspecfit-qa fastspec.fits
