Neutrino Factory Physics Study: Points in parameter space

To facilitate the detailed study of the physics capabilities of a neutrino factory, the oscillation theory and scenarios group (group 3) are defining a handfull of points in parameter space for explicit study. The parameter points defined so far are listed below.
