Notes. (2) Area of the subregions defined in Sect. 2.2 (see also Figs. 1–2). Except for the full area, labeled as Total, the uncertainties reflect the inherent difficulty in defining the subregion outlines and are the basis for the uncertainties given in Cols. 5–8. (3) Temperature range measured on the dust temperature image of Fig. A.1 (see also Pouteau et al. 2022). (4) Column density range measured on the column density image of Fig. 1. (5) Subregion mass computed from the 1.3 mm and dust temperature images of Fig. A.1 (see also Pouteau et al. 2022) following Eq. (2). These values are lower limits for the MM51 and Outskirts subregions, and for the Total region (see Sect. 2.3). (6) Volume densities computed from Cols. 2 and 5 following Eq. (3). (7)–(8) Number and surface number density of cores, detected by Pouteau et al. (2022), which are located over subregion areas of Col. 2 (see also Fig. 2). (9) Cumulative mass of cores, taken from Table E.2 of Pouteau et al. (2022). Uncertainties arise from those associated with individual core mass estimates that depend on flux and temperature uncertainties, thus the ignoring uncertainties of Col. 7. (10) Concentration of subregion gas mass within cores computed from Cols. 5 and 9.
