For the two objects previously selected as examples (Figs. 2 and 3), we display the evolution with redshift of five different quantities. From top to bottom, total mass M_tot, stellar mass M_*, stellar-to-total mass ratio M_*/M_tot, gas mass M_gas and distance to cluster centre in units of cluster radius, r/R₂₀₀ . The vertical blue and orange dotted lines indicate minima in the distance to centre after infall, i.e. pericentres of the orbit, which can be seen correspond to minima in M_tot and maxima in M_*/M_tot. The stellar mass and stellar-to-total mass ratio of the object at z = 0 are indicated in the fourth panel. The horizontal dotted line in the bottom panel indicates the distance r = R₂₀₀, i.e., pointing to the infall to the cluster. The infall redshift of both objects is indicated in each plot with a dark vertical dashed line.
