For Zeta Pup, the final table in Stefan's thesis indicates:
    vinf   = 2350 km/s
    beta  = 0.8
    vturb = 0.10 * vinf = 235 km/s

Note that Stefan has a different (better) way of implementing "turbulence" than coded in
the standard Lamers SEI method.  Stefan doesn't assume that vturb is constant through the
wind, which produces some artifacts (shifts of the emission peak).  Instead, it turns on at
a particular radius and increases linearly with velocity thereafter.
