Scaling relations between the cluster mass, M_cl, and the mass embedded in the sphere of influence (M_inf, left panel) and turnaround mass (M_ta, right panel). Symbol sizes are proportional to the number of all filaments connected to a cluster, N_fil. Dark red symbols show clusters with a high percentage of quiescent galaxies, and light red and orange symbols show clusters with a lower percentage of quiescent galaxies (light red – A1367, and orange – A1185). Dashed lines show 1σ errors of the linear fit, and error bars show mass errors (Table 2). Numbers are order numbers of a cluster from Table 2.
