In detail the z is the HSC z1 filter, which seems to be a narrow z.The r-z cut is good at selecting red galaxies at z ~ 0.8.
With stellar locusCut IICut IA side benefit is that wedon’t really need to do stargalaxy separation, especiallyfor Cut II and Cut III.Cut III11Finally it is worth noting that stars will not be much of a problem with a cuts like these,simply because they are offset in z-H from the galaxy population.
