  1. Review of 2XMMp data products Anja Schröder, Univ of Leicester, UK John Pye, Univ of Leicester, UK

  2. List of 2XMMp data products • EPIC images and exposure maps: • bands 1 – 5 and band 8 (total band) • EPIC source time series • fits file and pdf plot • EPIC source spectra • fits source and background spectra • arf file • pdf plots • ACDS finding charts • Catalogue thumbnails and location images • Catalogue source summary html pages

  3. EPIC Source Specific Products (SSP)

  4. SSP extraction: *PNS003SRCREG0001.ASC src: r = 28” bgd: 60” ≤ r ≤ 180” exclude sources from background: DET_ML > 15 with r = 60”

  5. EPIC spectrum products • FITS file with grouped source spectrum [especget, grppha]: P<obsid><exp>SRSPEC0<jkl>.FIT • FITS file with background spectrum [especget]: P<obsid><exp>BGSPEC0<jkl>.FIT • FITS file with source ARF [especget]: P<obsid><exp>SRCARF0<jkl>.FIT • Spectral plot [XSPEC]: P<obsid><exp>SPCPLT0<jkl>.PDF • Canned RMFs available at SOC webside (-> keyword)

  6. EPIC source spectrum plots (pdf) MOS2 PN MOS1

  7. EPIC - time series products • FITS file with corrected TS for the source (minus background), background TS, FRACEXP and variability keywords [lccorr, ekstest]: P<obsid><exp>SRCTSR8<jkl>.FIT • Graphics plot (source TS, background TS, fracexp and flare TS) [elcplot]: P<obsid><exp>STSPLT8<jkl>.PDF • FFT plot (filtered by aligned flare GTIs) [efftplot]: P<obsid><exp>SFFTPL8<jkl>.PDF

  8. EPIC source time series plots TS plot FFT plot 2 test

  9. Science with 2XMMp time series

  10. 2XMMp Cool-Star Variability Survey Poster by J. Pye, A. Schröder, I. Stewart, N. Webb, D. Fyfe Tycho catalogue: ~2.5 million stars, V < ~13 mag -> in 2XMMp: ~2000 objects -> with TS: ~500 objects -> with obvious flares: ~40 objects -> serendipitous sources: ~10 objects

  11. 2XMMp Cool-Star Variability Survey: Example I HD 14716: V = 9.5mag, F5V 5 other XMM observations (total of ~60 ks) show X-ray emission at quiescent level

  12. 2XMMp Cool-Star Variability Survey: Example II 2MASS J04072181-1210033: V = 11.7mag, (B-V) ~ 0.5 2 XMM observations 2 days apart

  13. 2XMMp Cool-Star Variability Survey: Example III UY ScI: Chen et al 2006 (ApJ 131, 990): -> W UMa-type binary (P ~ 31ks, d=389 pc) => XMM PN exposure duration ~ binary period

  14. 2XMMp Cool-Star Variability Survey: Example IV XMM MOS1 XMM OM UVM2 filter (manual extraction)
