Maximal halos in high-luminosity spiral galaxies
Received 30 October 1997 / Accepted 18 March 1999
We test the halo dominated mass model, recently proposed for high-luminosity galaxies, against the rotation velocity data of a large sample of 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.
