For the community

The X-IFU Consortium produced several resources that are made available to the scientific community.

X-IFU response matrices (2018)

The latest X-IFU response matrices produced by Didier Barret/Edoardo Cucchetti (IRAP) and verified by the Bamberg group led by Joern Wilms, with the support of the system team, including Philippe Peille.
These files have been produced for the so-called Athena cost-constrained configuration, with a diameter corresponding to a peak effective area at 1 keV of ~1.4 square meters. The response files cover 50 eV to 12.5 keV but the
usual range for the fits should be 0.2-12 keV. Please check the FITs headers to see the assumptions used. Check also the README file, and look at the PDF files.

Further information can be found in the following paper: Barret et al. (SPIE, 2018). Please contact us for any enquiries.

If you have used the X-IFU response matrices in a research project, please refer to: Barret+ (2021 in prep).

X-IFU background files

The X-IFU background files are produced by the IAPS/INAF group led by Simone Lotti. The files reflect on the X-IFU response matrices (see above) for the so-called Athena cost-constrained mission configuration.
The files are available for point and extended sources:

  • an extraction surface of 78,5 arcsec^2 (for point sources corresponding to an extraction radius of 5arcsec)
  • an extraction surface of 1 arcmin^2 (for extended sources)

Please directly contact Simone Lotti for any further information.

New set of X-IFU resources

A new set of X-IFU resources will be published in February 2022.
