VLA contour images of the 3.6 cm emission associated with DG Tau for the epochs 1994.29 (top) and 1996.98 (bottom). The images were made with the weighting parameter ROBUST = 0. The contours are –3, 3, 4, 6, 8, 10, 12, 15, 20, and 25 times 19 and 15 μJy beam-1, the rms noises of the 1994.29 and 1996.98 images, respectively. The crosses mark the position of the star, determined as described in the text. The beams are shown in the bottom left corner and their dimensions are given in Table 1.
