Notes. The columns are (1) source ID, (2) sample (see Sect. 4), (3) rotational temperature, (4, 5) kinetic temperatures from the methods by Ott et al. (2011) (Tkin,O) and Tafalla et al. (2004) (Tkin,T), (6–8) NH3 column densities from the methods of Friesen et al. (2009) (Ntot,Fr) and Lu et al. (2014) (Ntot,L), (9) gas pressure ratio, (10) virial mass, (11) virial parameter, (12) excitation temperature from Eq. (4), (13) H2 volume density. The excitation temperature values marked with an asterisk denote the five sources where due to their τ =0.1 lower limit, their original values have been replaced with the median excitation temperature of the rest of the cores, 4.5 K.
