Fe XVII 17.051, 17.096 Angstroms

Models with isotropic porosity

Note: We fit only the MEG data. There are 402 MEG 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=2.32e-3. The 68% confidence limits on the normalization are +/- 4e-4. And the best fit is formally a good fit. View the spectral region near the line: MEG.

line ratio fixed at 0.9

Fe XVII 17.051, 17.096: isporous MEG; line ratio fixed at 0.9 [16.93:17.20], λo = 17.051, 17.096
powerlaw continuum, n=2; norm=2.32e-3
hinf=0.39   +/- (0.00:2.92) and for 90%
      confidence, (0.00:5.13)

taustar=2.87   +/- (1.89:7.90)
uo=0.664   +/- (0.551:0.99)
norm=1.72e-4, 1.55e-4 +/- (1.61e-4:1.81e-4)
rejection probability = 94% (C=140.51; N=108)

Here are the 68%, 90%, and 95% joint confidence limits on taustar and uo. The asterisk represents the best-fit model, shown as the red histograms on the above plot.

Fe XVII 17.051, 17.096: joint hinf taustar constraints using MEG data; isoporous; line ratio fixed at 0.9
