zall-tilecumulative-SPECPROD.fits

Summary:

Concatenation of all ztile-*-cumulative.fits files.

Naming Convention:

zall-tilecumulative-{SPECPROD}.fits, where {SPECPROD} is the official name of the full reduction, e.g. fuji.

Regex:

zall-tilecumulative-[a-z0-9_-]+\.fits

File Type:

FITS, 2 GB

This file contains a concatenation of all input ztile-*-cumulative.fits files, combining redshift catalog entries across TILEs, SURVEYs and PROGRAMs. It additionally adds a column SV_PRIMARY to indicate the best recommended redshift if the same TARGETID appears multiple times, and SV_NSPEC for how many times each target appears.

e.g. if the same Survey Validation TARGETID was observed on two different tiles, it will appear as separate redshifts in separate ztile files, and will appear twice in this file with one of the entries having SV_PRIMARY==True. Any target that appears only once will also have SV_PRIMARY==True.
