Environmental dependence of Q.E. Left panel: dependence of all masses. Middle and right panels: dependence in two subsamples divided by stellar mass. The total number of galaxies in the two subsamples are the same. The number to the left of each data point is number of RQGs in this mass bin, while the number to the right is the number of SFGs. The total number of SFGs or RQGs in the middle and the right panels is the same as the number of the cluster candidates in the left panel. Errors are propagated based on the Poisson statistics for each population in each bin.
