Notes. For sources known under multiple designations, the alternative designation not used in this work is provided in italics below the source name. The errors correspond to 1σ confidence intervals. The dust temperature of HGAL 284.015−00.857 is not given by Schuller et al. (2009), hence it is fixed to 35 K, a typical temperature of sources in the sample. ^(a) XCLASS assumes LTE, such that T_rot = T_ex = T_kin, further we assume T_rot = T_dust from Schuller et al. (2009), ^(b) $R_{1} = \frac{N (H^{35} C l)}{N (H^{37} C l)}$ ${R_1} = {{N({H^{35}}Cl)} \over {N({H^{37}}Cl)}}$ , ^(c) $R_{2} = \frac{\int^{} T_{mb} (H^{35} Cl) d v}{\int^{} T_{mb} (H^{37} Cl) d v}$ ${R_2} = {{\mathop \smallint \nolimits^ {T_{{\rm{mb}}}}\left( {{{\rm{H}}^{35}}{\rm{Cl}}} \right){\rm{d}}v} \over {\mathop \smallint \nolimits^ {T_{{\rm{mb}}}}\left( {{{\rm{H}}^{37}}{\rm{Cl}}} \right){\rm{d}}v}}$ integrated over ±15 km s⁻¹ around the main HFS line, guaranteeing to cover all three HFS lines. This range, however, slightly excludes the wings of the outflow components, but evades contamination from species such as SO⁺. ^(d) 3σ upper limits derived for non-detections, assuming optically thin, beam-filled emission and line widths of 5 km s⁻¹ for the core and 10 km s⁻¹ for the outflow.
