Top: Stacked 43 GHz image from observations in 2007−2009, rotated by 16° clockwise. It is convolved with a circular beam of 0.15 mas. Contours represent isophotes at 0.3, 0.6, 1.2, 2.4, 4.8, 9.6, 19.2, 38.4, 76.8, and 153.6 mJy/beam. The four maps were aligned to the position of component N, as shown in Fig. 1. Bottom: double peaked intensity profiles at the location of the cuts indicated in the top image.
