Notes. Teff is in kK; log g is the gravity without centrifugal correction; YHe denotes thehelium fraction by number used in the simulations; and υ, R* and max are in units of km s−1, R and 10−6 M yr−1, respectively. gives the maximum possible clumping factor in Region 4 still consistent with the data. log Q′ = log (max/R*1.5) is in units of M yr−1 and R, and, for clarity, the last column indicates the label for the solution displayed in Figures A.2 and A.6.
