Notes. (a) The adopted period from Table 3 (np = non-periodic, sat = saturated data). (b) Assumed to be the same as the median value for the inner-GB sample. (c) The uncertainty is estimated to be a factor of 5. (d) The gas-to-dust mass ratio estimated as 
. The uncertainty is estimated to be a factor of 7. (e) Estimated as weighted averages of the results for the detected CO lines. The uncertainties are estimated to be ± 1.0 and ± 1.5 km s−1 for the systemic and expansion velocities, respectively. A colon indicates an uncertain value. (f) The uncertainty is estimated to be a factor of four. A colon indicates an uncertain value.
