Notes. For component A, we provide the best-fit values for the assumption of a PL spectral model and an ECPL spectral model. σ, e, and ϕ denote the 1-σ radius, eccentricity, and position angle of the Gaussian spatial model, respectively. N0, Γ, E0, and Ec are parameters of the spectral models, as defined in Eqs. (1) and (2). Systematic uncertainties have been derived as described in Appendix B.
