Ne IX 11.544 Angstroms

Non-porous models

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.

Continuum fit on 11.3:11.4 and 11.65:11.85. View the spectral region near the line: MEG and HEG. For 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.

Ne IX 11.544: non-porous MEG
Ne IX 11.544: non-porous HEG
[11.44:11.64], λo = 11.544
powerlaw continuum, n=2; norm=1.64e-3
taustar=0.83   +/- (0.39:1.48)
uo=0.481   +/- (0.381:0.581)
norm=5.00e-5 +/- (4.5e-5:5.4e-5)
rejection probability = 63% (C=234.73; N=236)

Here are the 68%, 90%, and 95% joint confidence limits on taustar and uo 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 isotropic porosity models to the data. And after that, anisotropic porosity models.
