Lower panel: Distribution in stellar mass and luminosity at rest-frame wavelength 4.4 μm/(1 + z) with 3 ≤ z ≤ 4 for the final sample of 1202 galaxies. The best-fit relation with its 1σ dispersion are displayed in solid and dashed blue lines, respectively. The position of the F444W = 25 limiting magnitudes for z = 3 and z = 4 are shown with two golden lines. Upper panel: Evolution of completeness with stellar mass at the z = 4 luminosity limit. The horizontal golden line showing the 90% completeness level. Consequently, the green vertical line defines the estimated 90% mass completeness limit. Taking into account galaxies with low mass-to-light ratios, our sample is 99% complete for this population to the right of the red dotted line.
