Bar histogram of objects inside (top) and outside (bottom) the COSMOS X-ray groups from Gozaliasl et al. (2019) for 0.08 ≤ z < 1.53. The objects outside X-ray groups were selected by running a random number generator 1000 times with the same number of objects as the ones inside groups, and taking the mean and standard deviation. Red colour represents FRIIs, blue represents FRIs, green shows FRI/FRIIs, and black denotes COM AGN. The number of objects inside X-ray groups: 87 COM AGN, 12 FRII, 4 FRI/FRII, and 8 FRI. Outside the X-ray groups, the numbers are 68 ± 3.9 COM AGN, 9 ± 2.9 FRII, 3 ± 1.7 FRI/FRII, and 6 ± 2.3 FRI.
