XMM-Newton Current Calibration File: Updates

Back to Calibration Homepage

2004-07-28; Response files for both MOS and pn have been updated

pn

Further adjustments of the redistribution parameters in the Partial Event Model at low energies (<600 eV) were done.

MOS

Observations of calibration targets confirm a significant change in the low energy redistribution characteristics of the MOS cameras with time. This change is probably due to an increase in the surface charge loss property of the CCDs which degrades the low energy resolution. Epoch dependent calibration files have been produced which reflect these changes. For detailed information see XMM-SOC-CAL-SRN-169.
