Image Details
Caption: Figure 52.
Four 20 m L-band rasters of Orion A, Orion B, and Barnard’s Loop, separately background-subtracted, with a 20 beamwidth scale (larger than the minimum recommended scale from Table 1, given the size of Barnard’s Loop), time-delay-corrected, appended, jointly RFI-subtracted, with a 0.4 beamwidth scale (to preserve Airy rings), and surface-modeled, with a minimum weighting scale of 2/3 beamwidths. Logarithmic scaling is used to emphasize Barnard’s Loop and fainter sources.
