Mg XI 7.8503 Angstroms

Non-porous models

Note: Both MEG and HEG are being fit simultaneously. Emma Wollman did the model fitting. See the fitting log.

Continuum fit on 7.92:8.03. For n=2, best-fit norm=1.28e-3. The 90% confidence limits on the normalization are +/-0.1e-3. And the best fit is formally a good fit.

Mg XI 7.850: non-porous MEG
Mg XI 7.850: non-porous HEG
powerlaw continuum, n=2; norm=1.28e-3
taustar=0.65   +/- (0.33:0.84)
uo=0.751   +/- (0.691:0.836)
norm=1.33e-5 +/- (1.2e-5:1.5e-5)
rejection probability = 60% (C=136.92; N=124)

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.
