  • The remnant is covered by chip ACIS-S3(CCD_ID=7).
  • Due to usage of the subarray some part of the remnants are missing in some observation.
  • These observation were done with NO aspect dithering.
  • No background light curve filtering was done.
  • It seems that the central source is strongly affected by pileup.
