Notes.
We quote internal statistical uncertainties. The Teff and log g uncertainties for the pure-H models are similar to the solar z uncertainties. An analysis by Kepler et al. (2016) of the systematic uncertainties from multiple spectra indicated 5% in Teff and 0.05 dex in log g.
The fitting pipeline of Kepler et al. (2016) does not provide uncertainties for this fit because it does not agree with the cool Teff implied by the SDSS photometry for this star. We estimate the uncertainties by taking the difference between the parameters of the best fits to the tabulated Plate-MJD-Fiber and a second SDSS spectrum of this object, 3146-54773-0003.
