Fig. A.1
Output of the PyBDSM source finder tool. The axis units are in pixels. From left to right and from top to bottom: original image on which PyBDSM is run (in this example, the ID2 map of Table 3); islands of significant emission (cyan contours) and fitted Gaussians that model identified sources overlaid on the ID2 map; residual after the subtraction of the fitted sources; model of the reconstructed sky. The big red ellipse corresponds to the diffuse emission in the centre of the cluster.
