Notes. (1)Protocluster name, central position used for the ALMA-IMF observations. Distances and masses are from Motte et al. (2022) and references therein. (2)Velocity relative to the local standard of rest extracted from Cunningham et al. (2023). (3)Classification of the ALMA-IMF protocluster clouds: Young (Y), Intermediate (I), and Evolved (E) (see Section 4.1 by Motte et al. (2022)). (4)Central frequencies of observations in Band 6 extracted from Louvet et al. (2024). (5)Angular resolution in Band 6 extracted from Louvet et al. (2024). (6)Angular resolution in spw1 Band 6 (217.150 GHz, which includes the SiO (5–4) and DCN (3–2) lines) defined as θave=θmaj×θmin$\[\theta_{ave}=\sqrt{\theta_{maj} \times \theta_{min}}\]$ and extracted from Cunningham et al. (2023). (7)Angular resolution in spw5 Band 6 (230.530 GHz, which includes the CO(2–1) line) extracted from Cunningham et al. (2023).
