\tablefoot{Column~1: the core number as in Table~\ref{tab_a1} (numbers in boldface indicate the $M > 200$~\msun~cores). Column 2: the virial mass (see Sect.~4.2.2). Column 3: the internal turbulence (see Sect.~4.2.1). Column~4: the systemic velocity deduced from $^{13}$CS and/or H$^{13}$CO$^{+}$. Columns~5 to 8: the peak line intensity, the line width at half maximum, full line width at the base and integrated intensity of the SiO emission. Columns~9 to 12 (see Sect.~4.2.4): the asymetric parameter and the blue to red peak ratio of the HCO$^{+}$ and HNC lines. Asterisk in the $\delta$V$_{HCO^{+}}$ column indicates dense cores suspected to have several components present along the line of sight. Column~13: the possible nature of the source: Compact \hii\ region (C\hii\ region), ultra-compact \hii\ region (UC\hii\ region), hyper-compact \hii\ region (HC\hii\ region), IR-quiet protostar, IR-bright protostar, or starless core.} \vspace*{3mm} \end{table}
