Notes. (1)As reported in Sect. 2.1, Band 6 observations decontaminated from free-free emission were used in our analysis (Galván-Madrid et al., in prep.).(2)We indicate both the best (first) and coarsest (second) angular resolutions obtained with the ALMA-IMF observations.(3) ALMA Band 3 observations were not used in the PPMAP analysis, in order to prevent contamination by free-free emission (see Appendix A.1.3).
