Example reconstructed, segmented, and segregated images. Left: reconstructed image of a G = 14.0 magnitude primary source, located at (RA_p,Dec_p), into whose data four secondary sources, all 2 magnitudes fainter, have been injected. Centre: segmented image, the segment containing the brightest pixel is labelled 1. For clarity, the threshold level at which the segmentation stops has been increased for this plot, and a log-scale is used. Right: segregated image, here the blue crosses indicate the positions returned for the sources found in this image. A connection number of −1 or 0 means this image pixel belongs to the background and not a source. In all panels, the grey dashed circles indicate angular separations of 0.25, 0.50, 0.75, and 1.0″ from the centre of the image (and primary source position).
