Top: restored image comparison between Högbom CLEAN (left), MS-Clean (middle), and WAsp (right) on the Cyg A dataset, representing a real-data narrowband imaging test of scale modeling. Bottom: residual image comparison between Högbom CLEAN (left), MS-Clean (middle), and WAsp (right) on the Cyg A dataset, highlighting the improved convergence behavior and more noiselike residual structure obtained with WAsp. All images in each row are displayed at a common scale shown in the color bar on the right of each row.
