Table 1: Physical parameters of the 11 observed CHVCs. l and b are the Galactic longitude and latitude of the column density maximum, $\alpha$ and $\delta$ the corresponding equatorial coordinates, $v_{{\rm LSR}}$ and $v_{{\rm GSR}}$ the column density weighted average radial velocities in LSR and GSR frames, $\Delta v$ the average line width ( FWHM), $T_{{\rm B}}$ the observed peak brightness temperature, $N_{H {\sc i}}$ the H I peak column density, and e the ellipticity of the cloud. The last two rows give the mean value $\langle x \rangle$ and the standard deviation $\sigma _x$ for each parameter x.
