zall-pix-SPECPROD.fits

Summary:

Concatenation of all zpix-*.fits files.

Naming Convention:

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

Regex:

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

File Type:

FITS, 2 GB

This file contains a concatenation of all input zpix-*.fits files, combining redshift catalog entries across 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 during both Target Selection Validation (sv1) and the One-Percent Survey (sv3), it will appear as separate redshifts in separate zpix 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.
