Spatial distribution (contours and colour) of the SVS13-A region obtained using different SO2, and 34SO2 line emission (see Table 1). Angular offset are respect to the phase centre (see Sect. 3). The whole velocity emitting region has been used (from 0 km s−1 to +20 km s−1, see Fig. 7). The SO2(112,10–111,11) profile has been deblended by the CH3OCHO line fitting the profile with two Gaussians (see Table 1). First contour and steps are 5σ and 10σ, respectively. The 1σ value is: 7 mJy km s−1 for SO2 (81,7–80,8 (left panel), 14 mJy km s−1 for SO2 (112,10–111,11), SO2 (183,15–182,16), and 34SO2(120,12–111,11). The filled ellipse shows the synthesized beam (HPBW): 1.′′6 × 1.′′1 (PA = 41°) for the SO2(81,7–80,8) maps (left panel), and 0.′′65 × 0.′′58 (PA= –46°) for the other images. The black crosses indicate the positions of the VLA4A and VLA4B sources as imaged using the VLA array by Tobin et al. (2018).
