X-ray spectral model for the 2005 and 2007 Chandra data.
|Model||NH||Normalization||Γ or kT||C/d.o.f.|
Notes. The errors correspond to 68% confidence intervals. NH is kept frozen during the fit and is given in units of 1020 cm-2. The power-law normalization is in units of erg cm-2 s-1 at 1 keV. The neutron star atmosphere model normalization is in units of 106m2 and refers to a 90% confidence level upper limit.
