0.35-8.0 keV image from an 89 ks ACIS-S3 observation with the proposed extraction region overlaid. There are about 2.5 million total counts from the SNR in this data set.
Chandra image from a larger region that has been smoothed and contrast enhanced with the XIS extraction region overlaid to determine if there are any bright sources in the XIS extraction region: 
Fit to the ACIS spectrum with the ESAC version 1.0 model for the 2.0-10.0 keV range.
