Notes. Column description: 1: photon index assumed for the analysis. 2, 3: 95% CL flux upper limit on the stacked emission of the entire sample in units of 10-11 ph cm-2 s-1 and final TS value after 53 stacking steps. 4, 5: same as 2, 3 for the CC subsample. 6, 7: same as 2, 3 for the NCC subsample.
