[mesa-users] Error in Vink wind formula

[Bill Paxton]

Hi Roni,

Q: I checked again, and what is currently in mesa matches the Vink et al eqns 24 and 25,
so the terms you are providing are a correction to the paper?   Or is there something else
in the paper that I missed?  Or do I have the wrong paper?


thanks,
Bill
