## Models with anisotropic porosity

Note: Both MEG and HEG are fit simultaneously. There are 805 MEG counts and 271 HEG counts in the spectral region we fit (and plot below). See the fitting log. We eliminated the red wing beyond 12.18 due to blending with an iron line at 12.24.

Same continuum fit as we used for the non-porous and isoporous models: *n*=2, best-fit norm=1.64e-3. View the spectral region near the line: MEG or HEG.

This model is nearly identical to the best-fit non-porous model; any amount of porosity makes the fit worse. The confidence limits are very similar too. Anisotropic porosity seems to be strongly disfavored.

Here are the 68%, 90%, and 95% joint confidence limits on *h*_{inf} and taustar. The asterisk represents the best-fit model, shown as the red histograms on the above two plots.

Only very small values of the terminal porosity length are allowed.

And here are the joint constraints on taustar and *u*_{o}:

These are very, very similar to those found in the non-porous case.
