Notes. 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 center; (5) and (6): geometrical average between the major and minor FWHM sizes of the core (in pc), as measured in the high-resolution column density map after deconvolution from the 18.2″ HPBW resolution of the map and before deconvolution, 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 of the 500μm data, derived from a graybody 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) instead of the core radius measured prior to deconvolution; (17) Bonnor-Ebert mass ratio: αBE = MBE,crit/Mobs (see text for details); (18) core type: starless, prestellar, or protostellar; (19) comments may be “no SED fit”, “tentative bound”, or “CO high-V_LSR” (see text for details).
