Left panel: sensitivity map of the VLBA-COSMOS project. The colour bar represents the rms noise values in μJy/beam. The white crosses show the target positions. White contours are drawn at 10, 12, 15, 20, 25, 30, 34, and 40 μJy/beam to match the contours in the VLA image. Right panel: Fig. 4 from Schinnerer et al. (2010), representing the sensitivity map of the VLA-COSMOS Deep project. The contours correspond to rms levels of 10, 12, 15, 20, 25, 30, 34, and 40 μJy/beam. We can see that the rms distribution of the two images is in excellent agreement.
