(a) Background-subtracted (NXB, CXB, and GH) SSC all-sky image in the 4–7 keV range. (b) Sky distribution of the relative NXB intensity, to be used in rescaling the NXB spectral map. (c) 4–7 keV SSC map, obtained by subtracting the scaled NXB spectral map |$N_\mathrm{s}^{\prime }(\vec{i}, E)$|, instead of subtracting |$N_\mathrm{s}(\vec{i}, E)$| as used in panel (a).
