Notes.
The assignment of the quality flags to the redshifts is the same as was adopted by G10 and M12. We also adopted the flag “c” for the redshifts corresponding to galaxies belonging to the protocluster. The flag “c” is not present for the redshifts from G10 and M12, although the galaxies from G10 and M12 are all defined as protocluster members.
