Stellar mass as a function of redshift. Top panel: Observed stellar masses (gray dots) and corresponding limiting masses (black dots) of all galaxies. Middle and bottom panels: Same relations for star-forming (blue) and quiescent (red) galaxies, respectively. Open circles mark the 95th percentiles of the limiting-mass distributions in redshift bins of width Δz = 0.01. Solid curves show the best-fit completeness relations for the corresponding subsamples, while dashed curves show the fits for the other subsamples. We adopt the quiescent-galaxy fit (red curve) as the stellar-mass completeness limit for the full sample.
