Abstract HectoMAP is a dense, red-selected redshift survey to limiting r = 21.3 mag covering 55 deg 2 in contiguous 1.°5 strip across the northern sky. This region also covered by Subaru/Hyper Suprime-Cam (HSC) Subaru Strategic Program photometric enabling range of applications that combine dense foreground with both strong and weak lensing maps. The median exceeds 0.3 throughout region, mean d...
