Uncertainties for vx and vy as a function of H magnitude for stars with colors H − Ks > 1.3 on the Brick field. We considered only stars with velocity uncertainties smaller than 2 mas yr−1 (red dashed line). We did not consider stars with an absolute difference in magnitude with GNS bigger than 0.5 (red dots). We applied the same criteria in both fields.
