Notes. Velocities and line widths, with the errors estimated by the Gaussian fitting algorithm in CLASS are provided in Cols. 2 and 3. Making the assumption that the cloud radius is equal to the beamsize, virial masses are calculated as in Braine et al. (1997a) and the errors using only the uncertainty in . Masses from the CO(1-0) line intensity are given in Col. 5 using the line area from Table 2a and a ``standard'' galactic conversion . The first 4 clouds have Gaussian fits made using the 2.6 km s^-1 channel width whereas the latter 7 fits have been made using data at 0.52 km s^-1 channel width. Cloud 8 appears to have two velocity components, producing the broad line. Cloud 2 has a large error associated with the CO(1-0) observation; the Gaussian fit to the CO(2-1) line yields a width of  km s^-1but the CO(2-1) beam is much smaller and may not include all the emission.
