Distributions of K-band magnitude, stellar mass and photometric redshift for the sample of K_AB< 23, z> 1.3 passive galaxies. Three leftmost panels: full sample (see text, black line), its pBzK subsample (red line), and the spectroscopic sample (scaled by × 10, red shaded area). Vertical dotted lines show the magnitude and mass (at z< 2.5) completeness limits of the parent K-selected catalog (see text). Rightmost panel: full photo-z distribution of the K_AB< 23 passive sample (black line), and of its log(M/M_⊙) > 10.9 subsample (shaded area, lighter gray at z> 2.5 where sample is beyond mass completeness).
