Notes. Table columns are as follows: Col. 1: name of the system; Col. 2: known distance, or range of plausible distances, in Mpc; Col. 3: H i mass in units of 10⁵M_⊙; Col. 4: rotation velocity in km s^-1; Col. 5: H i radius in kpc. For the UCHVCs this is the extent to which the velocity motion can be reliably traced in the 210′′ and 105′′ data; Col. 6: dynamical mass in units of 10⁷M_⊙, derived as described in the text above; Col. 7: the ratio of H i mass to dynamical mass.
