Each entry in the redshift catalog is described by 14 tags. In the ASCII version of the catalog, each tag comprises a space-deliminated column. Note that there can be multiple entries in the redshift catalog for a given object. Each entry corresponds to a particular observation of that object designated by the IMACS slitmask (given by MASKNAME), the slit number on the mask (SLITNAME), and the date of observation (MJD). Below, we provide a basic description of each tag. Note that in most instances (e.g., when computing rest-frame quantities) one should use the heliocentric-corrected redshift value (ZHELIO) versus the observed value (Z).
