Major changes to low energy calibration for EPIC cameras planned.

(See poster on EPIC cross-calibration…M.P.Esquej et al. this meeting)

MOS: For the next SAS release rmfgen will be modified to generate

rmfs for the MOS detectors which are epoch AND spatially dependant.

PN: Shows no significant evolution of the rmf or arf with time but a

change in the absolute rmf is being implemented to improve low energy calibration.

Summary

Major advances in the EPIC low energy cross-calibration soon to be implemented

suggest a more robust determination of the spectral shape/model of the soft

excess in 3C 273 can be made.

The EPIC view of the hard X-ray data suggest that the nonthermal component

is dominant over the “accretion” component, probably more so than suggested by

the recent published analysis of BeppoSAX results.
