Fig. B.2


Channels map of the SO(65–54) blue- and redshifted (continuum subtracted) emissions towards IRAS2A. Each panel shows the emission integrated over a velocity interval of 2.7 km s-1 centred at the value given in the upper-right corner. Symbols are drawn as in Fig. 2. The ellipse in the top-left panel shows the PdBI synthesised beam (HPBW): (PA = 33°). First contours and steps correspond to 5σ (15 mJy beam-1 km s-1) and 10σ, respectively. Grey lines indicate the slowing down of the highest velocity SO clump (see text).
