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.
Fit to the ACIS spectrum with the ESAC version 1.0 model for the 2.0-10.0 keV range.
Fit with the ESAC version v1.0 model in the 2.0-4.0 kV range looking for any missing lines, there do not appear to be any line features that the ACIS spectrum would require:
