Left: contour plots of the flux of the Fe Kα₁ line versus the velocity of the line in km s^–1 where the Compton shoulder is fit with a step function. Right: FWHM of the Fe Kα₁ line versus the velocity of the line in km s^–1. Note that the centroid and the width of the Fe Kα₂ line are tied to the Fe Kα₁ line as described in L. Barragán et al. (2009).
