Local density distributions. The gray histogram represents the distribution of log ₁₀(Σ_vor/ Mpc²) for the parent galaxy sample from Scoville et al. (2013) at 0.75 <z< 1.2. The purple histogram shows the density distribution of our sample. Both histograms are re-normalized for a better visual comparison of their spreads and peaks, therefore their normalization does not reflect the actual scale. The vertical line splits in half the parent local density distribution, to define the low- (to the left) and the high- (to the right) density environments. The plot embedded shows the comparison of the two cumulative distributions of both samples with the resulting value from the K-S test.
