Each shell has thermal energy of the order of $10^{49-50}$ erg. Several CO-line shells are associated, whose kinetic energies are of the order of $10^{49-50}$ erg. Summing up the energies of recognized GCSs, the total energy amounts to $\\sim 10^{51}$ erg. The GCSs show an excellent correlation with the FIR shel","authors_text":"Univ.
