Table 1: Interferometric positions and fluxes of the continuum emission at 1 mm and 3 mm from the single field data set (2000/01) and the central field of the mosaic observations from 2001/02 ( right column). The difference in the 3 mm flux densities between the first epoch and the second is discussed in the text (Sect. 3.1.1).
Table 2: Positions and fluxes for CO(1-0) components in the PdBI+30 m map. Offsets are with respect to $\alpha _{2000}$ = 11h32m34.8 and $\delta _{2000}$ = 53 $^\circ$ 04'04.9''.
