Left: Radio surface brightness (I_R) vs. X-ray surface brightness (I_X) for band 3. The points in these plots are from the grid shown in Figure B.1. The cyan points are from the northern X-ray tail, the red points are from the southern X-ray tail, and the remaining points are from the rest of the halo. The fit to the points is shown as a solid black line, and the 95% confidence region is shown in the shaded part. The dashed red line shows the 1σ level of the radio images. The light blue arrows indicate the upper limits above 2σ_rms points. Right:I_R vs. I_X scaling plot for band 4 in the same color-code as in the left panel.
