Left: three-color image, with 4–6 keV Chandra data in red (binned by a factor of eight), 8–10 keV deconvolved NuSTAR data in green, and 10–20 keV deconvolved NuSTAR data in blue. The hardest X-rays are brightest in the west of the SNR and coincide with the non-thermal X-ray “stripes” (denoted by the large red rectangle) seen in the deep Chandra data and analyzed by Eriksen et al. (2011). The small rectangle corresponds to the “hook” of non-thermal emission described in the text. Right: three-color image, with 4–6 keV Chandra data in red, 10–20 keV deconvolved NuSTAR data in green, and 20-cm VLA data in blue. We note that the NuSTAR, Chandra, and VLA images have pixel sizes of 2.″5, 3.″9, and 4.″2, respectively.
