Some nights/exposures have problems that are fixable (or at least ameliorated) by non-standard processing options that we don't want to apply to all exposures. Although this could be done by hand for…

iron/tiles/cumulative/82405/20211118/coadd-8-82405-thru20211118.fits has a bunch of spectra with a negative turnover at large wavelengths:
 examples of large discrepancies. The worst case is:

Irsic et al. (2017) provides a covariance for different redshift bins, and Karacayli will do as well.
Owr p1d_data_base assumes that we have a list of covariances for each redsfhit, we might need …

Compared to the first two deep ELG tiles, there is a trend for ELG spectra on tile 80610 to show more frequently strong skyline residuals, generally above 9300AA but in some cases already from 8300AA.…
