HectoMAP: the complete redshift survey (DR2)

The survey covers 54.64deg^2^ in a 1.5{deg} wide strip across the northern sky centered at a decl. of 43.25{deg}. We report the redshift, the spectral indicator Dn4000, and the stellar mass.

The red-selected survey is 81% complete for 55,962 galaxies with (g-r)>1 and r<20.5; it is 72% complete for 32,908 galaxies with (g-r)>1, (r-i)>0.5 and 20.5<r<21.3. Comparison of the survey basis SDSS photometry with the HSC-SSP photometry demonstrates that HectoMAP provides complete magnitude-limited surveys based on either photometric system. We update the comparison between the HSC-SSP photometric redshifts with HectoMAP spectroscopic redshifts; the comparison demonstrates that the HSC-SSP photometric redshifts have improved between the second and third data releases.
