====================== 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 :doc:`zpix-*.fits <./zpix-SURVEY-PROGRAM>` 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``.
