bsens continuum map at 1.3 mm obtained with ALMA, with cores from the getsf filtered core catalogue. The colours now represent the different categories of cores that we identified: free-free contaminated cores in dark green, free-free dominated cores in light green, and ‘uncertain’ cores (see Sect. 4.2) in neutral green. Outflow knots/CO-contaminated cores (see Sect. 4.3) are shown in blue, hot core candidates (see Sect. 5.1) in red, cores associated with outflows (see Sect. 5.2) in yellow, and the remaining prestellar cores in black, following scenario A (see text, Sect. 5.2).
