"Where's the Fe?"

• Use Astro-H responses[*] to generate a fake "E0102-IACHEC" spectrum
  and fit it with a single vpshock model with the 4 elements: O, Ne, Mg, and Fe.
  6/25/12: Added the 6-1 to 10-1 transitions of O VII and O VIII to the vpshock model --
  this gives better agreement in the 0.7 to 0.9 keV range while still needing some Fe:
  • Fake-data w/model (Green w/Fe, Magenta no Fe): vs Energy , vs Wavelength
  • Plot of just the vpshock's Fe emission, vs Energy
  • Best-fit par file: kT ~ 0.75 keV, tau ~ 2e11, O,Ne,Mg,Fe ~ 1.9, 3.2, 1.6, 0.33 (with H=He=C=N=1).
  • For reference, this is the ISIS routine that was used to make fake data, plots, etc.
    The extra O lines are in the par file above and were initially added using some extra code.
  [*] files: sxt-s_100208_ts02um_of_intallpxl.arf and ah_sxs_7ev_basefilt_20090216.rmf .
• Add merged 3-epochs images to show the
  • "Fe" Residuals in the 2D spectral images.

Three-Epoch's of HETG-E0102 Data

• 28 May'12: And finally, set osipfile=none when making the ARFs (steps_e0102_src_120525.txt),
  and extend range to 2 keV (10 bins). The osip=none makes a few percent change:
  
  • N9941-contam No-OSIP [w/7arfs] ratios (.txt)
    • N9941-11-3_results_plot (.pdf)
• 20 April'12: Updated to use average of 7 arf's along the cross-dispersion direction,
  improved the rmf somewhat, and reprocessed obsid 12147 to use newest version (DS 8.4).
  --> These changes produced only very small changes:
  • N9941-contam [w/7arfs] ratios (.txt), as compared with N9941-contam ratios (.txt)
    The bottom lines of these .txt files give the average values for each epoch
    and for all epochs combined.
  • Comparing the results for various contamination models:

    • N0004-11-3_results_plot (.pdf)
  • PHA plots, Obsid 12147: MEG -1 (S1,S2), MEG +1 (S4)
  • The gARFs, including the FRACEXPO bpix corrections, are shown:
    . . . obsid 12147 (.pdf) . . . '3828(.pdf) . . . '968(.pdf) . . . '120(.pdf)
    In each panel, seven different arfs spanning the E0102 cross-dispersion range are plotted in red,
    the average gARF is overplotted in light blue.
    The dark blue curve is the average of the arfs without FRACEXPO included.

• The analyses of Jan'12 were re-done using both the CALDB(4.4.7) and the N9941 contam file(s):

  • Modified files since Jan'12 are in: PHA_sw_inc120326 .
  • Updated source extraction steps (to make alternate arfs): Source.

• Initial results (.txt) from doing fancy fitting in ISIS. See Notes in the .txt file.
• Example plots for Obsid 3828 MEG -1: Overall plot, Residuals plot.
  Key to Overall plot: Dispersed events histogram (black),
  E0102 model spectrum (green), ARF no-FRACEXPO (magenta),
  Forward-folded model w/custom RMF (orange), Coarse data bins (blue), Coarse fit-model bins (red).
  The residual plot shows just the coarse data bins (black) and the best-fit model bins (red).
