Download data from classic Seyfert galaxies (e.g., NGC 3227, Fairall 9, NGC 2992, NGC 4151, Mrk 3) and fit power-law models to 2-10 keV spectrum - Add additional absorber, esp. for Sy 2s - Compare diskline and gaussian fits to Fe-K - Does Fe-K EW vary between observations? Repeat Fe-K diskline simulation shown in the "Low-resolution X-Ray Spectroscopy" presentation (http://cxc.harvard.edu/xrayschool/talks/lowres-agn-spec.pdf): how many counts are needed before diskline becomes statistically distinct from a broad Gaussian? Simulate partial covering models at various numbers of counts (100, 500, 1000, 5000) - Fit with a simple power law, see how "effective" photon index for a simple power-law fit varies with scattering fraction and NH of the highly absorbed component
