Notes. Only two sources are listed as example, the complete tables, one for each of the three regions, are available at the CDS. Table entries are as follows: (1): core running number; (2): core name = HGBS-J prefix followed by a tag created from the J2000 sexagesimal coordinates; (3) and (4): right ascension and declination of core centre; (5) and (6): geometrical average between the major and minor FWHM sizes of the core, as measured in the high-resolution column density map after deconvolution from the 18.′′ 2 HPBW resolution ofthe map and before deconvolution, respectively (NB: both values provide estimates of the objects outer radius when the core can be approximately described by a Gaussian distribution, as is the case for a critical Bonnor–Ebert spheroid); (7): estimated core mass assuming the dust opacity law advocated by Roy et al. (2014); (9) SED dust temperature; (8) and (10): statistical errors on the mass and temperature, respectively, including calibration uncertainties, but excluding dust opacity uncertainties; (11): peak H2 column density, at the resolution ofthe 500 μm data, derived from a grey-body SED fit to the core peak flux densities measured in a common 36.′′ 3 beam at all wavelengths; (12): average column density, calculated as , where Mcore is the estimated core mass (Col. 7), Rcore the estimated core radius prior to deconvolution (Col. 6), and μ = 2.8; (13): average column density calculated in the same way as for Col. 12 but using the deconvolved core radius (Col. 5) instead of the core radius measured prior to deconvolution; (14): beam-averaged peak volume density at the resolution of the 500 μm data, derived from the peak column density (Col. 11) assuming a Gaussian spherical distribution: ; (15): average volume density, calculated as , using the estimated core radius prior to deconvolution; (16): average volume density, calculated in the same way as for Col. 15 but using the deconvolved core radius (Col. 5); (17): Bonnor–Ebert mass ratio: αBE = MBE,critMobs (see text for details); (18): core type: starless, prestellar, or protostellar; (19): comments may be “no SED fit” or tentative bound (see text for details).
