XMM-Newton Current Calibration File: Updates


Back to Calibration Homepage

2002-04-29; New version of the PN responses


EPIC-PN response files for small window and large window mode are now also available. Response files for timing mode and burst mode will be available soon.

As before there are response matrices for spectra selected from single-pixel events only, doubles only, and single+doubles combined, all for an event threshold of 20 adu. For instance, for full frame mode (ff):
 

epn_ff20_dY9_medium.rmf doubles selected from CCD lines 180-199, medium filter
epn_ff20_dY9_thick.rmf same, thick filter
epn_ff20_dY9_thin.rmf same, thin filter
epn_ff20_dY9_closed.rmf same, no filter, no telescope areas (useful for cal source)
epn_ff20_dY9.rmf same, pure redistribution, normalised to 1, without double fraction applied.
Read also this update.
epn_ff20_sY9_medium.rmf singles selected from CCD lines 180-199, medium filter
epn_ff20_sdY9_medium.rmf singles+doubles from CCD lines 180-199, medium filter

Extended full frame mode is indicated with the epn_ef prefix, small window mode with epn_sw, large window mode with epn_lw.

Files for ten CCD areas depending on the distance from the readout node are provided, and they are labelled as follows:

  • Y0 CCD lines 0-19
  • Y1 CCD lines 20-39
  • ...
  • Y9 CCD lines 180-199

All these files are under the ccd directory.

The files designated with the filter, thin, medium, and thick, are response files which have combined the spectral response matrices (RMFs) with the on-axis effective areas (ARFs), having the extension rsp. They are under the directories labelled with the filter name (eg. medium).

For off axis sources a user supplied ARF (i.e., from arfgen) should be used in conjunction with the pure redistribution matrix (*.rmf).
