Note. ^a Not guide IRAS source. Luminosity calculated based on IRAS fluxes and distance: 03260+3111 at 0.4 kpc (Harju et al. 1998) and 20151+3911 at 1.7 kpc (Motte et al. 2007). ^b Average spectrum fitted with two Gaussian profiles, list the stronger one. ^c No ¹²CO data, density calculated by assuming reasonable $T_{\rm ex}$ (see text). ^m Core's angular diameter comparable to beamwidth, marginally resolved. ^s Sourceless core. ^u Upper limit. $^\dagger$ Average calculating does not include values of marginally resolved cores, except for the line width column. ^* $\alpha = M_{\rm vir}$ / $M_{{\rm LTE}}$ .
