Vertical intensity profile z of H₂ CS (black) compared with those of CS(5–4) (red) and o-H₂CO(3_1,2−2_1,1) (blue), from Podio et al. (2020a). Only fluxes above 3σ confidence are shown. The H₂CS intensity has been scaled in order to better compare its profile with those of o-H₂ CO and CS. The inner 1′′.8 region is shown, with the positive (negative) values sampling the eastern (western) side. The angular resolution is 0′′. 25 (40 au). The profiles are obtained at ~60 au (upper panel) and 115 au (lower panel) from the protostar.
