\begin{table}%T2
\caption{\label{tab_results}Galactic longitude and latitude (in degrees),  velocity (km~s$^{-1}$), widths (km~s$^{-1}$), and intensities (K) of the CS~lines. In addition, the SiO~to CS~intensity ratio is also shown. The numbers in  parentheses are the uncertainties on the last digit. The positions observed with the IRAM~30~m telescope are indicated with a 
superscript. All the other positions have been observed with the 12~m telescope.}
