Robust weighted images of the continuum emission (grey scale) and CO J = 2−1 integrated flux (contours) at a resolution of 2.9′′ × 1.9′′. Continuum emission has been estimated from the 230.904 GHz setup in the ranges not affected by CO or 13CS. The stars represent the position of the 1.3 mm continuum sources from the high resolution images of Sakamoto et al. (1999). Contours are 3σ significant levels of 14 mJy beam-1 and 49 Jy km s-1 for the continuum and line flux, respectively.
