The HXD team has adjusted the high voltage setting of the PIN diodes and/or the low energy threshold 9 times so far during the mission lifetime. For each epoch, it is necessary to use:

  • the appropriate PIN threshold calibration file with hxdgrade during processing (true for all sequences currently available at HEASARC, proprietary or public)
  • the appropriately created PIN background model files (true for all NXB files currently available); and
  • the appropriate response files in data analysis (user responsibility)

The response files for Epochs 1-11 can be obtained through Suzaku CALDB. Further details regarding epochs can be found in this HXD CALDB Memo. Note, however, that the boundary between Epochs 1 & 2 listed in this memo (2006.05.13) is incorrect, and the value in the table above (2006.06.25) is correct.
