Fig. 3
Contour plots of the detected sources. Three images per source are shown in a
row. Left column: naturally-weighted images made with a
10 Mλ tapering (restoring beam size
55.5 × 22.1 mas2); middle column: untapered,
naturally-weighted image (restoring beam size 28.6 × 9.3 mas2);
right column: uniformly-weighted image (restoring beam
20.8 × 5.9 mas2). Positive contours start at three times the rms
level of the images and increase by factors of
. One negative contour is shown at
three times the rms.
