Notes. From left to right the columns are: the source identifier, the source designation, the source coordinates (J2000), their systemic velocities (based on that observed for the H13CO+ (7–6) line), their heliocentric and galactocentric distances, and the observed continuum temperature (i.e. the average main beam temperature of line-free channels) around the H35Cl (J = 1–0) line. The labels in the first column are used in Fig. 2. Systemic velocities that are marked with an asterisk are taken from Giannetti et al. (2014) using C17O while that of G291.272–00.714 is taken from Urquhart et al. (2007) and determined using 13CO. The Galactic heliocentric distances have been taken from Jacob et al. (2022) and references therein and cross-checked with version 2 of the parallax-based distance calculator on Appendix A from Reid et al. (2019).
