Processing details on the field of view shown in Fig. 8. Top left: shadowgram corrected for the background contribution using the wavelet method without source processing; the contribution of the bright source Sco X-1 remains visible. Top right: shadowgram corrected for the background using the wavelet method followed by the direct fit of the illumination function of the bright known sources (the same non-transformed illumination functions as used for the simultaneous fit with the CXB); the contribution of the bright source is only partially removed by this fit. Bottom left: illumination function (non-transformed) for a source in the partially coded field of view (used for the direct fit). Bottom right: transformed illumination function by the à trous wavelet-filter; this is the function to be fitted after the wavelet correction of the CXB in order to correctly remove the bright source contribution (as shown in Fig. 8, bottom right).
