Table 3:

A general comparison of the mock catalogues and samples from S84.
Sample $n_{\rm G}$ $n_{+ \Delta z}$ $n_{- \Delta z}$ $n_{\pm \Delta z}$ $+ \Delta z$ (%) $- \Delta z$ (%) $\pm \Delta z$ (%)
S84, all groups ($n \leq 10$) 85 42 32 11 57.0 43.0 12.9
S84, E/S0 dominant groups removed 60 33 18 9 65.0 35.0 15.0
S84, E/S0 dominant groups 21 9 10 2 47.0 53.0 9.5
Mock1, all groups ($n \leq 10$) 1384 622 505 257 55.2 $\pm$ 5.1 44.8 $\pm$ 5.1 18.6 $\pm$ 1.9
Mock1, spiral ( $T \geq 0.92$) dominant groups 1153 528 408 217 56.4 $\pm$ 5.6 43.6 $\pm$ 5.6 18.8 $\pm$ 2.4
Mock1, E/S0 (T < 0.92) dominant groups 231 94 97 40 49.2 $\pm$ 6.9 50.8 $\pm$ 6.9 17.3 $\pm$ 4.2
Mock2, all groups ($n \leq 10$) 12 100 5087 4658 2355 52.2 $\pm$ 1.3 47.8 $\pm$ 1.3 19.5 $\pm$ 0.6
Mock2, spiral ( $T \geq 0.92$) dominant groups 9086 3854 3466 1748 52.5 $\pm$ 1.8 47.3 $\pm$ 1.6 19.2 $\pm$ 0.8
Mock2, E/S0 (T < 0.92) dominant groups 3013 1179 1227 607 49.0 $\pm$ 1.8 51.0 $\pm$ 1.8 20.1 $\pm$ 2.0
Note: Sample refers either to S84, Mock1 or Mock2 catalogues, $n_{\rm G}$ is the number of groups, $n_{+ \Delta z}$ is the number of groups with positive redshift excess, $n_{- \Delta z}$ is the number of groups with negative redshift excess, $n_{\pm \Delta z}$ is the number of groups with no excess, $+ \Delta z$ is the percentage of groups with positive redshift excess when ties have been removed, $- \Delta z$ is the percentage of groups with negative redshift excess when ties have been removed and $\pm \Delta z$ is the percentage of groups having equal number of negative and positive redshifts. Errors for mock catalogues are standard deviation errors between five different observation points.
