Red symbols show the estimated median density as a function of redshift for our sample galaxies. To minimize the cosmic variance, median densities are estimated within ±0.2 redshift intervals at each redshift. The uncertainties are 1.4826 × the median absolute deviation from the median values. The black solid line shows the estimated median density over the whole field (﹩0.1\lt z\lt 1.2﹩) and the black dashed lines show its upper and lower uncertainties. We find that within the uncertainties, the median values do not change much with redshift. This emphasizes a volume-limited-like sample selection to avoid any unrealistic underestimation of the density values at higher z as a result of missing fainter, less-massive galaxies.
