ACIS-S spectra for the X-ray counterpart of the pulsar (panel a)) and the entire PWN (panel b)). The solid lines correspond to the respective best-fit spectral models (absorbed blackbody and absorbed power law, respectively). In the panel a), the pulsar blackbody component (red) and the nebular contribution in the same region (green) are shown. The unbinned spectrum fitted using C-statistics has been rebinned in the plot for visual clarity.
