Notes. $v_{\rm LSR}$ , $\Delta v$ and $T^*_{\rm A}$ of the OCS lines shown in Fig. 8 (see text, Sect. 4.1) derived from three Gaussian fits.
⁽¹⁾ Due to line overlap only the ridge component can be fitted; ⁽²⁾ although the line is clearly present, the derived parameters are biased by the presence of nearby lines from other species.
