2–10 keV spectra of the Type 2 AGN Centaurus A, extracted and aperture-corrected from 3″–5″ annuli in ACIS-I ObsIDs 7800 (black) and 8489 (red), fitted by the model described in Eq. (1). The top panel shows the spectra and model-to-data ratio in instrument units while the bottom panel shows the unfolded spectra. The spectra are attenuated by strong absorption. The sole emission line is the 6.4 keV Fe Kα line.
