Models with isotropic porosity
Note: We fit only the MEG data. There are 225 MEG counts in the spectral region we fit (and plot below). See the fitting log. We fit the resonance and intercombination lines; the forbidden line isn't detected.
Same continuum fit as we used for the non-porous models: n=2, best-fit norm=1.87e-3. The 68% confidence limits on the normalization are +/- 4e-4. And the best fit is formally a good fit.
Here are the 68%, 90%, and 95% joint confidence limits on hinf and taustar. The asterisk represents the best-fit model, shown as the red histograms on the above plot.
There are essentially no joint constraints here. Note that more "normal" values of uo possible with porosity.
Next, we fit anisotropic porosity models - we report only the fitting log here.
