Hi David,

do you know if our hotel reservations from Sunday - Thursday nights?

Also, when are you getting to Berlin?

It's not ready yet. I'll finish on the plane or in Berlin. Maybe we can go over it together briefly in Potsdam, or maybe I can get it to you by email on Friday.

OK, I'm attaching the plot I made. The four different cross section plots are for different radii. The bottom red one is at the base of the wind; the next black one is around 1.5 R_*; the next red one is around 5 R_*; and the top black one is around 100 R_*. However, since these are for the ionization balance of AV83, they may not be quite right for Zeta Pup. The main variable will be the He ionization fraction. I would guess that the bottom red curve is probably the closest to the main part of Zeta Pup's wind, but who knows?
