CQ Tau continuum maps in mm-cm bands from our new high angular resolution data (from top left to bottom right): 0.87 mm, 1.3 mm, 2.7 mm, 7 mm (from Testi et al. 2003), 1.3 cm, 3.6 cm maps. In each plot the position of the central star and the beam ellipse are shown. Contours levels are spaced by 2σ where σ is 9 mJy at 0.87 mm, 1 mJy at 1.3 mm, 0.3 mJy at 2.7 mm, 0.1 mJy at 7 mm, 0.02 mJy at 1.3 cm and 0.009 mJy at 3.6 cm. All maps have been corrected from their original epoch to the epoch 2000.0, using the proper motion of the optical star as measured by Hipparcos (RA: 2.67, Dec: –26.17 mas/year), the star is also plotted at the epoch 2000.0 coordinates, as given by Simbad at CDS.
