Notes. The definition and optimisation of the model of the γ-ray sky describing the data is carried out through an iterative (n-step) process, starting with model 0 including the background map normalised to 1, the unresolved large-scale Galatic emission contribution, and the two point sources HESS J1745−290 and G0.9+0.1; then at each step of the fit a new component is added to improve the modelisation of the emission. At each step, a significance map of the residual and a TS map is created, allowing us to search for features that should be included in the model. Details of the more relevant parameter values are given for 4 steps of the fitting process. The 68% confidence intervals of the parameters are also indicated. The significance of the component detections are indicated by the value of ΔTS /d.o.f. and converted into equivalent significances. The CSTAT/d.o.f. goodness of fit is given as an indication of the fit quality improvement at each step of the iterative procedure.
