Notes. Emission peaks of SiO(2–1), SO(23−12), CS(2−1), and CH3OH(2kk−1kk). We report the spatial offsets (Δ α, Δ δ) and distance (d) with respect to the coordinates of the driving protostar (see Table 2), the peak velocity in the spectra extracted at the emission peaks (Vpeak−Vsys), the velocity integrated intensities (∫ TB dV), and the column densities (N). (a)Assuming a kinetic temperature of 100 K. (b)The methanol velocity integrated emission refers to the sum of the blended (20,2−10,1) E, (20,2−10,1) A, and (21,1−11,0) E emission lines (see Sect. 5.3). The peak velocity was measured from the (20,2−10,1) A profile.
