Notes. These cores were identified and classified using the standard HGBS procedure described by Könyves et al. (2015). We note that RA and Dec are the centroid equatorial coordinates of the cores, and the cores are sorted from west to east; HL and HS are the major and minor axes of the elliptical Gaussian source that was fit to each core in the Herschel high-resolution (18.2″) column density map; PA is the position angle of the major axis (measured east of north); Rdec is the deconvolved core radius;
is the peak column density;
is the ratio of the peak to background column density; and Mcore
is the core mass estimated from SED fitting. When a core is protostellar,
Mcore is the protostellar envelope mass. Last MBE
is the critical Bonnor-Ebert (BE) mass and R-PRE, C-PRE, U-STA, and PRO stand for the robust prestellar core, the candidate prestellar core, the unbound starless core, and the protostellar core, respectively. There are 24 U-STA cores, 11 C-PRE cores, 20 R-PRE cores, and two PRO cores in total.
