Red- and blue-shifted bipolar SVS13-B jet as traced by SiO(2–1) is shown in magenta and is compared with CH₃OH(2_kk−1_kk) (left panel), SO(2₃−1₂) (middle panel), and CS(2–1) (right panel). The methanol emission is due to the lines of the 2_kk−1_kk spectral pattern that emits at 96.7 GHz (see Table 1). The SiO and SO maps were obtained by integrating on the following velocity ranges with respect to the systemic velocity (+8.5 km s⁻¹; Podio et al. 2021): ± 33.8 km s⁻¹ (SiO), ± 23.6 km s⁻¹ (SO), and from −18.3 km s⁻¹ to +6.1 km s⁻¹ (CS) (see Fig. 3). The first contours and steps are at 3σ, which corresponds to 72 mJy km s⁻¹ beam⁻¹(SiO), 45 mJy km s⁻¹ beam⁻¹(CH₃OH), and 63 mJy km s⁻¹ beam⁻¹ (SO, and CS). The positions of the B continuum peak are marked by a black triangle (Table 2). The crosses mark for each species the peaks of the red- and blue-shifted emission (see labels). The synthesised beams are shown in the bottom-left corners, and the dashed circles delimitate the FoV (Table 1). For SiO, the dataset with the beam of 2″.56 × 2″.14 was used for a proper comparison with SO, CS, and CH₃OH.
