Images at the 0.5-2 keV energy band of all the ObsID (marked on the top left in each panel), centred on the QSO ID1. The images are binned to one-fourth of the native pixel size and smoothed using a Gaussian kernel of 3 sub-pixels. The green 2″ circle indicates the QSO centre, which was used for alignment across observations. The number of counts in the 0.5-2 keV energy band within the 2″ circles is shown on the top right corners in each panel.
