Comparison of continuum-subtracted Fe Kα radial profiles per quadrant (q1, q2, q3, and q4, as defined in Appendix Fig. F.4) for all the sources in the sample. The profiles have been divided by 25% of the renormlized HERX1 radial profile used in Fig. F.2, such that azimuthally symmetric profiles consistent with the PSF should have values consistent with 1 at all radii. The errors plotted are 99.987% confidence. The radial bins of the different quadrants have been shifted slightly so that the error bars are easier to compare.
