BL Lac reconstructions with DoB-CLEAN blurred with the clean beam with natural weighting (left panel), uniform weighting (middle panel) and uniform weighting with smaller pixel size zoomed in the central core region (right panel). The contour levels are: [0.1,0.2,0.4,0.8,1.6,3.2,6.4,12.8,25.6,51.2]% ([0.1,0.2,0.4,0.8,1.6,3.2,6.4,12.8,25.6,51.2]%, [0.8,1.6,3.2,6.4,12.8,25.6,51.2]%) of the respective peak brightness.
