Stellar mass completeness as a function of galaxy (U−V) rest-frame colors for the whole COSMOS Wall sample limited to K_AB ≤ 22.6 (bottom panel) and for the subset limited at I_AB ≤ 22.5 (top panel), which reproduces the completeness of the 20 K-sample. Left hand panels display the actual galaxy stellar mass distribution, while the right hand panels show the limiting masses for each galaxy, all as a function of (U−V) rest-frame colors, plotted on the y axis. The dashed lines represent the mass limits estimates.
