Notes. Columns: (1) core running number; (2) name = HGBS_J followed by J2000 source coordinates in sexagesimal format; (3) and (4) J2000 RA and Dec of source centre; (5) and (6) geometrical average of the two FWHMs measured in the high-resolution column density map, after and before deconvolution with HPBW of 18′′. 2, 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 the critical Bonnor-Ebert spheroid); (7) and (8) estimated core mass; (9) and (10) SED dust temperature; (11) peak H2 column density, at the resolution of 500 μm intensity map, derived from a modified blackbody 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 after deconvolution (Col. 5), μ = 2.8; (13) average column density, calculated is the same way as for Col. (12), but using the observed radius (Col. 6); (14) beam-averaged peak volume density at the resolution of 500 μm intensity map, derived from the peak column density (Col. 11) assuming a Gaussian spherical distribution:
; (15) average volume density, calculated as
using the estimated core radius after deconvolution; (16) average volume density calculated as previous column but using the observed core radius; (17) Bonnor-Ebert mass ratio αBE = MBE,crit∕Mobs; (18) core type: starless, prestellar or protostellar; (19) comments. Full catalog is at CDS.
