VLA contour images of the 3.6 cm emission associated with DG Tau for the epoch 2009.62. The image was made with the weighting parameter ROBUST = 5 to emphasize extended structure. The contours are –3, 3, 4, 6, 8, 10, 12, 15, 20, 30, 40, 60, 80, and 100 25 times 8.8 μJy beam-1, the rms noise of the image. The cross marks the position of the star, determined as described in the text. The beam is shown in the bottom left corner and its dimensions are given in Table 1.
