Caption: Figure 38.

20 m L-band raster from Figure 5 background-subtracted, with 7 (left; Table 1) and 24 (right) beamwidth scales (Figure 23), and RFI-subtracted, with a 0.9 beamwidth scale (Table 2). RFI, both long-duration intersecting 3C 273 and short-duration near Virgo A, as well as en-route drift across the entire image, is successfully eliminated. Locally modeled surfaces have been applied for visualization, with a minimum weighting scale of 2/3 beamwidths (Section 1.2.1; see Section 3.7). Hyperbolic arcsine scaling is used to emphasize fainter structures.
