This function visualizes the merit.function
as a
function of v
and sigma
around specified values p
(in general the best-fit values).

The function computes merit.function
on a grid of 20x20
of velocity and velocity dispersion. The resulting matrix is either
plotted as a contour plot or returned along with the velocity and
velocity dispersion vectors.
