1 XMM-Newton Extended Source Analysis Software Steve Snowden & Kip Kuntz  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 Spectra Particle 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 extensions Mosaicking of multiple observations Extension to PN data

2 XMM-Newton Extended Source Analysis Software Tool to process and filter data sets to remove obvious soft proton flaring. A1795 Observation

3 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. Filter wheel closed spectrum Red: Abell 1975 spectrum Green: Model particle background spectrum

4 XMM-Newton Extended Source Analysis Software The quiescent particle background is significant at higher energies even for bright and hard sources. A1795 Spectrum Fitted background subtracted spectrum Same fit as above but without the background subtracted from the data

5 XMM-Newton Extended Source Analysis Software Other background components can also be significant over various energy ranges. A1795 Spectrum at the 5-7 arc minute annulus. Black: Data and Full Model Red: Cluster Emission Dark Blue: SXRB emission Green: Instrumental Lines Light Blue: Soft Proton

6 XMM-Newton Extended Source Analysis Software Different observatories and different methods, and different results. A1795 XMM- Newton and Chandra Spectra. Green: Chandra results from Vikhlinin et al Blue: XMM-Newton results from Nevalainen et al Red: XMM-ESAS

7 XMM-Newton Extended Source Analysis Software Background subtracted, exposure corrected, and Adaptively smoothed image of Abell 1795 in the keV band.

8 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.
