  1. Plasma models of calibration sources at high resolution Andy PollockXMM-Newton RGS Calibration ScientistIACHEC High-Resolution Working Group ATOMDB Work Week @ CfA 2012 August 6-10

  2. HETG spectra and old APEC model of Capella MEG HEG

  3. HETG spectra and old APEC model of Capella MEG HEG

  4. Deconstructing X-ray models of Capella • Data • Chandra HETG, then RGS, then LETG • Calibration • Appropriate response files • Ion-based decomposition of ATOMDB • Bound transitions • emission lines (λ,f) • DR • RRC • 2-photon continuum • Free-free electron continuum • Methods to explore parameter space • XSPEC+Tcl or ISIS+S-lang

  5. >1000 lines + 90 continua  ~2500 DOFs for Capella ATOMDB v2.0.2 MEG N=8192 Σn=510316 n≤5948 C-Statistic=74814.6 HEG N=8192 Σn=133800 n≤634 C-Statistic=42305.5

  8. 1Ms RGS spectrum of SNR 1E0102-7219

  9. 1Ms RGS spectrum of SNR 1E0102-7219

  10. WR140 : the hot-star Capella MEG HEG WC7+O5 P=8yr e=0.9 • 1/D scaling • net • LX • NX • no H • abundances • fir ratios • line profiles

  11. WR140 : the hot-star Capella

  12. AtomDB items of interest • Capella  APEC • Good for observers • What do theorists say ? • Emission lines in SNRs, CWBs and other fancies • Out of equilibrium • Non-solar abundances • Resolved line profiles • Charge exchange (equilibrium) • SNR 1E0102-7219 challenge • Photoelectric absorption • “McClaughlin+ model” for Xspec • Use the C-statistic • χ2 is wrong
