Background model as a function of center distance for the detected sources in the soft band (a) and the full band (b). The red solid line shows the average smoothed background model with 1 uncertainties indicated by the red dashed lines, whereas the colored dotted lines show the extracted counts in the three control fields. The gradual decline as a function of off-center angle reflects the radial change in effective exposure time as shown in Figure 3.
