Notes. Values for Teff and log g from literature, unless otherwise indicated. Note that T1 and T2 are SPINOR best-fit temperatures corresponding to unit optical depth calculated for continuum opacity at 5000 Å. Overall best-fit results as well as 1σ and 3σ ranges determined for Bf, see text. 3σBf range rounded to 50 G.

*

log g used as free fit parameter.
