Abstract:
We have observed the oxygen rich supernova remnant E0102-72 every year since launch to monitor the low energy response of ACIS and to measure the build up of contamimation on the ACIS filters.

Remarks:
Dither: 8 arcsec amplitude. The E0102-72.3 observations need to be done with the old dither pattern for a direct comparision with previous observations.
