## Non-porous models - allowing *q* to be a free parameter

Here is the best-fit non-porous model shown already on the main page for this line. After that, we show results for the same model, but with *q* free.

That was for comparison. Here's the same model, but with *q* free:

The fit is slightly better (ΔC=1.9) than the fit with *q=0* frozen - *q*=0 is just outside the 68% confidence limit. The confidence range for taustar is slightly higher and *u*_{o} slightly lower.

Here are the 68%, 90%, and 95% joint confidence limits on taustar and *u*_{o} 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. The figure on the left is for the fit with *q* free and the one on the right is the one we've already shown, for *q*=0 frozen.
