AGN Triggering in the Infall Regions of Distant X-Ray Luminous Galaxy Clusters at
Figure 3
(a) Comparison of the stacked effective exposure time radial profile with respect to the defined image center positions in the cluster fields (blue solid line), the average control field (black solid line), and the three individual control fields (dotted lines). (b) Fractional difference of the stacked effective exposure time profile of the cluster field and the average control fields as a function of radial distance from the field centers (black solid line). The blue dashed line indicates the median exposure time difference of 11.3%, dotted lines depict the individual control fields as before.
