  1. EPIC-BG Working Group - At the end of the last UG meeting, and in line with the conclusions from previous UG meetings, it was highlighted that there is a need for EPIC to progress in the description and treatment of the EPIC-BG - Setting-up (June 05) of EPIC-BG working group: Andy Read (science chair), Jenny Carter, Wolfgang Pietsch, Michael Freyberg, Steve Snowden, Matthias Ehle/Marcus Kirsch (SOC) • Tasks: • Define requirements of BG material (s/w, templates files) useful for general user • Place general user BG material (tools, knowledge, files) on SOC web pages • Organize/monitor necessary work at the PI institutes • Hold regular BG status meetings • Liase with other groups working on BG-critical material

  2. EPIC-BG Meeting June/July `05 - Introduction We need to understand the components of the (EPIC) X-ray background We need to reduce as much as we can the (particle/instrumental) components of the X-ray background. This is relevant not just for EPIC, but for future missions also. We need to model as correctly as possible the remaining components of the X-ray background Understand – Reduce – Model

  3. Primary Actions (from 07/05 meeting): - To Provide to SOC: - Proton screening tool (+ use of multiple lightcurves for screening) - EPIC-supported primary BG tool - (List of Standard Candles for BG analysis) - Link to processed pn closed event files - Script(s) for BG Blank Sky data analysis (template files) - Implementation of BG Blank Sky data analysis scripts at ESAC - Set up prototype SOC BG web page (accessible from main page) - Update BG components main summary table • Minutes & presentations available on web page (+ other secondary actions…)

  4. BG Blank Sky data analysis Original pps product event file Source-removed, BG-flare-filtered, plus energy, pattern, flag & FOV filtering

  5. BG Blank Sky data analysis Corresponding exposure map of merged BG event file Merging of BG event files (e.g. 2 MOS2 FF Thin-filter files)

  6. Read & Ponman `03

  7. Next BG-WG meeting: November 24th-25th, MPE Garching

  8. Soft Proton flaring in an observation of a Galaxy Group

  9. SP X-ray vignetting Radial profile of the residual SP contamination (red points and a quadratic black model curve) compared to the vignetting function [Snowden]

  10. Updates and Additions to EPIC Background Products http://www.sr.bham.ac.uk/xmm3/BGproducts.html A&A 409, 395 (2003)

  11. - Thick filter blank-sky background event files now available Instrument Mode Filter NOBS Exp.time (s)
