peculiar velocity data imposed by the Zone of Avoidance. Furthermore, even though different in details, the gross features of the mass density field are similar to those obtained by applying either the same or the POTENT formalism to the Mark III catalog[@wfmark][@potentm3] and SFI catalogs[@dacostasc]. This is an outstanding result considering the different ways these catalogs were constructed and the peculiar velocities measured. Current results are also a remarkable improvement over those obtained from earlier catalogs. In particular, it is worth mentioning the prominence of the Perseus-Pisces region, completely absent in the earlier maps, and the well-defined voids, well-known features in redshift surveys which are now clearly seen in the reconstructed mass distribution.

The reconstructed three-dimensional velocity field can also be used to measure other quantities of interest. For instance, the amplitude of the bulk flow is found to vary from $V_{B} =300 \pm$ 70  for a sphere of $R=20\hmpc$ to $160 \pm$ 60  for $R=60\hmpc$. This value is in good agreement with that obtained from a direct fit to the radial peculiar velocities for the SFI[@sdipole] and the ENEAR[@edipole] samples. This result disagrees with the bulk flow determined for the Mark III survey, which has an amplitude of roughly
