Left panel: contour plots of the IRAS2A continuum emission at 1.4 mm. The ellipse shows the PdBI synthesised beam (HPBW): (PA = 33°). First contours and steps correspond to 5σ (7.5 mJy beam-1). Labels indicate the main source (MM1) and two weaker sources (MM2 and MM3). Middle panel: contour map of blue- (–39, +3 km s-1) and redshifted (+11, +21 km s-1) SiO(5–4) emissions superimposed on the SiO at low-velocity (+3, +11 km s-1; black contours). First contours correspond to 5σ and 10σ, followed by steps of 10σ. One σ is 84 (blue) , 15 (red), and 12 (black) mJy beam -1 km s-1. Crosses are for the position of the four SiO clumps (A, B, C, and D; see Figs. 2 and B.3). Magenta triangles stand for the positions of MM1, MM2, and MM3. Grey lines are the directions of the PV diagrams shown in Figs. 2 and B.3. Right panel: same as middle panel for the SO(65–54), averaged over (–29, +3), (+11, +19), and (+3, +11) km s-1 for the blue-, red-, and black-velocity, respectively. One σ is 86 (blue), 18 (red), and 16 (low-velocity) mJy beam-1 km s-1.
