Caption: Figure 43.

Background-subtracted 20 m L-band raster of Cassiopeia A from Figure 27 RFI-subtracted (1) with the maximum recommended RFI-subtraction scale from Table 2 (0.8 beamwidths), which partially eliminates the first Airy ring (left), and (2) with half of this scale, which retains this structure (right). Locally modeled surfaces have been applied for visualization, with a minimum weighting scale of 1/3 beamwidths (Section 1.2.1; see Section 3.7). Square-root scaling is used to emphasize fainter structures.
