Ne X 12.134 Angstroms

Non-porous models - excluding more of the red wing

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 excluding λ>12.16 from the fit.

Ne X 12.134: non-porous MEG
Ne X 12.134: non-porous HEG 		[12.03:12.18], λo = 12.1339
vinf=2250
β=1
powerlaw continuum, n=2; norm=1.64e-3
q=0
hinf=0
taustar=2.03   +/- (1.75:2.27)
uo=0.681   +/- (0.631:0.731)
norm=2.69e-4 +/- (2.62e-4:2.80e-4)
rejection probability = 63% (C=191.35; N=176)

That was for comparison. Here's the same model, but fit on a narrower wavelength range:

Ne X 12.134: non-porous smaller wavelength range MEG
Ne X 12.134: non-porous smaller wavelength range HEG 		[12.03:12.18], λo = 12.1339
vinf=2250
β=1
powerlaw continuum, n=2; norm=1.64e-3
q=0
hinf=0
taustar=1.96   +/- (1.69:2.21)
uo=0.660   +/- (0.615:0.712)
norm=2.74e-4 +/- (2.64e-4:2.84e-4)
rejection probability = 65% (C=169.01; N=149)

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. The figure on the left is for the fit with the new, more restricted, wavelength range and the one on the right is the one we've already shown, for the bigger wavelength range.

Ne X 12.134: joint uo taustar constraints using MEG+HEG data; smaller wavelength range Ne X 12.134: joint uo taustar constraints using MEG+HEG data

Changing the wavelength range over which we fit the data hardly changed the fit at all.
