## Non-porous models

Note: Both MEG and HEG are being fit simultaneously. See the fitting log. We used the *hewind* model, which fits the three components with separate wind profile models in which the relevant parameters are tied together, including the radius-dependent relative emissivities of the forbidden and intercombination lines. In other words, the line ratios and line shapes are self-consistently accounted for.

Continuum fit on 6.40:6.55 and 6.82:6.95. View the spectral region near the line: MEG and HEG. For *n*=2, best-fit norm=9.26e-4. The 68% confidence limits on the normalization are +/- 0.5e-4. And the best fit is formally a good fit (though not as good as usual; see the fitting log linked above; we tried several different continuum fits). We used a value of *phiratio* = 17.8 for the fit reported below.

Here are the 68%, 90%, and 95% joint confidence limits on taustar and *u*_{o}. The filled circle represents the best-fit model, shown as the red histograms on the above plots.

We fit porous models to this line complex but found that the porosity length was very poorly constrained; basically unconstrained.
