Morphology-density relation in all three MAMMOTH protoclusters. BOSS1244 is shown in red. BOSS1542 is shown in black. BOSS1441 is shown in green. With the exception of the additional point for BOSS1441, the figure is identical to Fig. 5. As in Fig. 5, the values of the fractions of galaxies with n ≥ 2 for each sample is measured by bootstrapping over the measured errors in Sérsic index over 1000 iterations.
