Line profiles in CS(2–1), and SO(2₃−1₂), in brightness temperature scale, towards the peak of the CS emission in the SVS13-A southern molecular shell: α(J2000) = 03^h 29^m 05^s.317, δ(J2000) = +31^∘ 15′30″.09. The black vertical line at +8.5 km s⁻¹ is for the systemic emissions. The CS lines is brighter than the SO one, although a word of caution is needed given the position lies outside the FoV of the images.
