Cumulative luminosity function for apparent magnitude in H-band at z = 1 of the satellite galaxies from all halo clusters with M_halo > 10¹⁴ M_⊙ in the coincident regions of all flavours of simulations available in this work. The bottom panel shows the ratio compared to the 7K-GIZMO simulations. The vertical orange line represents the observational limit for EUCLID. The vertical green line represents the beginning of the loss of the power-law slope for 15K-SAG.
