Notes. Columns are as follows: (1): Global luminosity–density D8 range; (2): Number of galaxies in corresponding global luminosity–density range; (3–4): Median value of the stellar mass, , and p-value of the KS test between a given population in the lowest global density environment (D8 ≤ 1) and in the given global density interval; (5–6): Median value of the stellar velocity dispersion σ^* and p-value of the KS test as in column (3); (7–8): Median value of the concentration index C and p-value of the KS test as in column (3); (9–10): Median value of the D_n(4000) index, D_n(4000)_med, and p-value of the KS test as in column (3); (11–12): Median value of the star formation rate, SFR_med, and p-value of the KS test as in column (3).
