CEN1A: Chandra grating spectrum

6.182 Angstroms: Si XIV Ly-alpha

This is the original wgauss + powerlaw model fit, to a narrower wavelength range.

wgauss + pow

MEG
Si XIV: MEG
HEG
Si XIV: HEG 		 
fit on [6.10:6.26]
continuum powerlaw n = 2, norm = 1.75e-4
wavelength = 6.182 A
sigma = 28.71 mA   +/- (24.36:34.45)
      corresp. to 1393 km/s   +/- (1182:1672)
delta = -1.82 mA   +/- (-7.10:3.52)
      corresp. to -88 km/s   +/- (-345:171)
norm = 2.88e-6   +/- (2.47e-6:3.36e-6)
rejection probability = ???% (C=177.20; N=188)

For the higher terminal velocity of 3000 km/s:

MEG
Si XIV: MEG 		 
fit on [6.10:6.26]
continuum powerlaw n = 2, norm = 1.75e-4
wavelength = 6.182 A
taustar = 0.04   +/- (0.00:0.50)
Ro = 2.04 R*   +/- (1.75:2.54)
norm = 2.88e-6   +/- (2.40e-6:3.23e-6)
rejection probability = ???% (C=175.13; N=188)

And for the lower terminal velocity of 2500 km/s:

MEG
Si XIV: MEG 		 
fit on [6.10:6.26]
continuum powerlaw n = 2, norm = 1.75e-4
wavelength = 6.182 A
taustar = 0.15   +/- (0.00:1.36)
Ro = 3.15 R*   +/- (2.24:6.01)
norm = 2.85e-6   +/- (2.37e-6:3.20e-6)
rejection probability = ???% (C=174.69; N=188)
