BL Lac reconstructions with DoB-CLEAN at full resolution with natural weighting (left pane), 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]% ([0.025, 0.05, 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.
