v1
The v1 redshift catalogs combine redshifts and classifications from individual redrock files with the corresponding target and observing metadata.
The ztile catalogs contain redshifts for each survey/program combination, fit to coadded exposures of each tile (but not coadded across tiles). The zpix catalogs are similar to the ztile catalogs, but they also coadd data across tiles before redshift fitting. The zall-pix and zall-tilecumulative catalogs stack the individual zpix and ztile files into combined catalogs across all surveys and programs.
