Results of the template-free reconstruction based on model M1. The figure uses the spectral domain color mapping introduced in the caption of Fig. 2 and Appendix C. It highlights spectral variations in the reconstructed skies. The color scale is provided in the bottom panel of Fig. 2. First row: reconstructed gamma-ray sky. Second row: separated diffuse emission (left) and PS sky (right). Third row: absolute uncertainties of the diffuse component (left), the full gamma-ray sky (middle), and the PS component (right). The maps follow a Mollweide projection. Single energy bin maps of the diffuse emission component are provided in Fig. D.1.
