Models with isotropic porosity
Note: Both MEG and HEG are fit simultaneously. There are 333 MEG counts and 102 HEG counts in the spectral region we fit (and plot below). See the fitting log.
Same continuum fit as we used for the non-porous models: n=2, best-fit norm=2.55e-3. The 68% confidence limits on the normalization are +/- 1.5e-4. And the best fit is formally a good fit. View the spectral region near the line: MEG and HEG.
Note that the improvement in C compared to the non-porous model is only 0.09.
Here are the 68%, 90%, and 95% joint confidence limits on hinf and taustar based on fitting the MEG and HEG data together. The asterisk represents the best-fit model, shown as the red histograms on the above two plots.
Next, we fit anisotropic porosity models.
