Notes. (a) Temperature derived from the rotational diagram method when possible (see Sect. 4.1). (b) Mass, Mcore, column density, Ncore, volume density, ncore, and surface density, Σcore, estimated using a dust temperature equal to Trot, and a dust opacity of 1.75 cm2 g-1 at 870 μm (see Sect. 4.1).
