Notes. For a sample with W1 < 14 we applied oversampling in all the extinction bins, while for W1 < 15 only for extinction in the range I100 ∈ ⟨ 3;10). Oversampling was implemented for quasars only. Parameters σW and σpm denote specific σ values of Gaussian distributions, respectively for magnitudes and proper motions.
