... Of course, both the finite angularsize and the finite 3 energy resolution of the detector will result in a distribution of energies associated with a particular scattering material. ...
... Moreover, the large angularsize (D25 ј 26 0 ) of NGC 5128 makes it hard to effectively remove contamination by foreground and background X-ray sources, which, given the depth of the exposure, account for about half of the detected sources ( Voss ...
