Fig. 4
3-mm image is overlaid with the contours of the 3-cm image derived from observations performed on 2011 January 25 (Ng. et al., in prep.), where the contours correspond to 20% flux-density intervals. Both the 3-mm and 3-cm images were restored with a 0.′′7 circular beam and are centred on the VLBI position of SN 1987A determined by Reynolds et al. (1995) (blue square).
