Morphology-stellar mass classification for a LSST-like survey (left panel) and for a DES-like survey (right panel). The black solid line is the measurement for the host cluster shown for visual reference. We only plot symbols and error bars for the range where we consider that the bias is below 10%. The subhalos are at d_M − S > 0.5 Mpc. Blue dotted lines correspond to galaxies with a relatively small bulge: Disk → 0 < L_Bulge/L_Total ≤ 0.6. Red dashed lines correspond to galaxies with a large bulge which spent more time inside a cluster: Bulge → 0.6 < L_Bulge/L_Total < 0.98. The different symbols distinguish different stellar mass bins (in units of 10¹⁰   M_⊙). For the left panel the ranges are: 1 →  [0.14:1.4 ] , II →  [1.4:4.11 ] , III →  [4.11:10.96 ] , 4 →  [10.96:∞ ] . For the right panel the ranges are I →  [1.1:4.1 ] , II →  [4.1:13.7 ] .
