Caption: Figure 40.

Background-subtracted and time-delay-corrected 40 ft noddings of Andromeda from Figure 24 (1) separately RFI-subtracted (left and middle) and (2) appended and then jointly RFI-subtracted (right), with a 0.7 beamwidth scale (Table 2). These maps are relatively free of RFI; as such, the appended map is nearly identical to what one gets from averaging the first two maps, but is nearly twice as efficient to produce, computationally (see below). 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).
