Comparison of the general properties of groups in the 0.2 ≤ z ≤ 0.45 (black dot-dashed line) and 0.45 < z ≤ 0.8 (red solid line) redshift bin. From left to right we compare Rfudge (the estimate of the virial radius), log ℳfudge (the estimate of the mass of the group), both fudge quantities are calibrated with the mocks as defined in Knobel et al. (2009), and 
, as defined in Sect. 5.1.
