All-sky approximate residual-significance map of the large-scale gamma-ray residuals. This map is intended only to visualize the large-scale residual morphology after baseline-template subtraction and is not used as a formal detection statistic. The background color shows ﹩({N}_{{\rm{obs}}}-{N}_{{\rm{model}}})/\sqrt{{N}_{{\rm{model}}}}﹩, constructed from the residual counts after the template fit and summed over the analyzed energy bins. The northern and southern hemispheres are fitted separately and merged for visualization. A 10° Gaussian smoothing kernel has been applied to highlight extended features. The overlaid contours represent the spatial templates for Loop I (yellow solid lines, M. Wolleben 2007) and the eBs (red dashed lines, P. Predehl et al. 2020). The Galactic plane region (∣b∣ < 15°) is masked to reduce contamination from foreground modeling uncertainties, with all masked regions assigned a numerical value of zero for visualization purposes.
