HectoMAP redshift survey DR1

This region is also covered by the Subaru/Hyper Suprime-Cam (HSC) Subaru Strategic Program photometric survey enabling a range of applications that combine a dense foreground redshift survey with both strong and weak lensing maps. The median redshift of HectoMAP exceeds 0.3 throughout the survey region, and the mean density of the redshift survey is ~2000 galaxies deg^-2^.

Here we report a total of 17,313 redshifts in a first data release covering 8.7deg^2^. We include the derived quantities D_n_4000 and stellar mass for nearly all of the objects. Among these galaxies, 8117 constitute a 79% complete red-selected subsample with r<=20.5mag, and an additional 4318 constitute a 68% complete red-selected subsample with 20.5<r(mag)<21.3.
