Notes. Images are from a combination of configurations A, B, and D arrays of NOEMA with the exception of pilot sources that lack D-array observations. (a)Robust weighting parameter using GILDAS definition whereby robust 0.1 corresponds to uniform weighting and robust 10 is closest to natural weighting. (b) Average linear resolution, using distances from Table 1. (c)rms noise in the emission-free region in the channel that has the peak of emission for CH3CN (124−114), therefore the unit is per 0.5 km s−1 channel. (d)Measured counterclockwise from the north-south axis. (e) Extent of the blueshifted emission for CH3CN (123−113). (f) Extent of the redshifted emission for CH3CN (123−113). (g)Sum of Rblue and Rred. (h)Pea_ velocity of CH3CN (123−113) at the position of the continuum peak. (i)Integration ranges for the moment maps shown in Fig. 2. (j) Isotopic ratios calculated according to Wilson & Rood (1994), (see text for details).
