Notes. Models tbabs*(apec+pshock), tbabs*(apec+apec), and tbabs*(apec+pow) for box2, the whole SNR, and PWN regions, respectively. All errors are shown with 90% confidence level. ne and nH are electron and H densities (cm−3), and D is the distance to the source. (a)The power-law component of the PWN region spectral model has index 
and a normalization 
ph keV−1 cm−2 s−1 at 1 keV.
