Spatial distribution (contours and colour) of the SVS13-A region obtained using different H2CS, and H2C34S line emission (see Table 1). The whole velocity emitting region has been used (from 0 km s−1 to +20 km s−1, see Fig. 11). The p-H2CS(62,4–52,3) emission has been deblended from the SO emission (see Table 1) applying two Gaussian profiles. Angular offset are relative to the phase centre (see Sect. 2). First contour and steps are 5σ and 10σ, respectively. The 1σ values (from left to right) are 5, 13, 11, and 9 mJy km s−1, respectively. The filled ellipse shows the synthesized beam (HPBW): 1.′′6 × 1.′′1 (PA= 41°) for the o-H2CS(31,3–21,2) line (left panel), and 0.′′65 × 0.′′58 (PA= –46°) for the p-H2CS(60,6–50,5), p-H2CS(62,4–52,3), and o-H2C34S(61,5–51,4) lines (middle and right panels). The black crosses indicate the positions of the VLA4A and VLA4B sources as imaged using the VLA array by Tobin et al. (2018).
