Publicly Released 5 April 2006 XMM-Newton Extended Source Analysis Software

Suite of Fortran 77 programs and Perl scripts EPIC Instruments (MOS for now) Particle Background Modeling

Position Dependent Background SpectraParticle background images

Creates exposure corrected, background subtracted, and adaptively smoothed images

Manual/Cookbook and spectral/imaging examples including suggested treatment for other background components

Future extensionsMosaicking of multiple observationsExtension to PN data

XMM-Newton Extended Source Analysis Software

Tool to process and filter data sets to remove obvious soft proton flaring.

XMM-Newton Extended Source Analysis Software

Tool to create quiescent particle background spectra.

A1795, Model Particle Background, and Filter Wheel Closed Spectra. The difference between the observed and background spectra at high energies is residual soft proton

contamination.

XMM-Newton Extended Source Analysis Software

Prototype mosaicking of Coma Cluster observations.

The data have been background subtracted, exposure corrected, normalized between adjacent pointings, and adaptively smoothed.
