Notes. Template, full table only provided at the CDS. Table entries are as follows: (1): core running number; (2): core name = HGBS_J prefix directly 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 (in pc), as measuredin the high-resolution column density map before deconvolution, and after deconvolution from the 18.2′′ HPBW resolution of the map, respectively(NB: both values provide estimates of the object’s 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 (M) assuming the dust opacity law advocated by Roy et al. (2014); (9): SED dust temperature (K); (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 greybody SED fit to the core peak flux densities measured in a common 36.3′′ beam at allwavelengths; (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 = 2.86; (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) instead of the core radius measured prior to deconvolution; (17) Bonnor–Ebert mass ratio: αBE = MBE,critMobs (see text for details); (18) Core type: 1 = unbound starless, 2 = prestellar, 3 = candidate prestellar (non-robust), 4 = dense core with embedded protostar, or −1 = tentative additional candidate core; (19): subregion using an arbitrary mask; (20): comments may be no SED fit, spatially unresolved in col. dens, low 250μm flux, low mass, or reflection nebula? (see text for details).
