Notes. (a) Region name. See Fig. 3. (b,c)Galactic longitude and latitude. (d)Region size. (e) Mean column densities derived from the CO and the HI integrated intensity (in the −71 to −41 km s−1 range), and the ionised gas. (f)Proton density derived from the mean column densities in Col. 5 using Np = N(H2) + N(HI) + N(HII). (g) Total mass of gas in each selected region.
