Put these on the R90-Rc diagram too. They look a lot more ellipsoidal than the others

Here are some examples:

Here is the circle fit to alpha Ori:

That is using --thmax 75, which I think is justified because of the low Rc/R0 = 1.45. It has R90/Rc = 1.43, which puts it in the prolate ellipsoid region of the diagnostic diagram, very close to the diagonal line.

Inclination of alpha Ori velocity vector

This is 50 deg according to Mohamed et al (2012). However, this need not be exactly the same as bowshock inclination angle if the ISM has a significant velocity (although probably not).
