The preliminary X-IFU background files were produced by the IAPS/INAF group led by Simone Lotti.
You may want to use these files to estimate the impact of the reduction of X-IFU effective area on your science. The documentation is available here and recipes to make new background files here, using the XSPEC model for the diffuse emission.
The files are available for:
- an extraction radius of 5 arcsec (for point sources)
- an extraction radius of 1 arc minute (for extended sources)
Please contact directly Simone Lotti for any further information.
