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
.
