Abstract
We test the halo dominated mass model, recently proposed for
high-luminosity galaxies, against the rotation velocity data of a
large sample of ![[FORMULA]](img1.gif)
spirals. We find that
this model does not reproduce the general kinematic properties
required. The alternative disc dominated model, on the contrary,
easily fits the data.
