Sample Stokes I images of two survey targets. (a) 610 MHz band image (zoomed in) of HD 189775, one of the unique detections from this survey. The noise in the image is ∼73 μJy. (b) Zoomed-in 1390 MHz band image of the target CPD –28° 2561, an example of a nondetection. The 3σ negative and positive levels are drawn with red and blue contours, respectively. However, the sizes of these contours are much smaller than the beam size (cyan ellipse near the lower left corner of each image) and are not reliable detections.
