Top panel: plot of L_X(gas)/L_FIR vs. interaction stage (open black squares). The X-ray luminosity in this plot has only been corrected for Galactic absorption, not for material within the host galaxy itself. Galaxies containing a Seyfert nucleus are circled in red. The galaxy with the highest L_X/L_FIR ratio is NGC 1700, which we classify as stage 7. Middle panel: plot of diffuse L_X(gas)/SFR vs. interaction stage, where the X-ray luminosity has only been corrected for Galactic absorption. Bottom panel: plot of diffuse L_X(gas)/SFR vs. interaction stage, where the X-ray luminosity has been corrected for absorption within the host galaxy itself, using the UV/mid-infrared ratio as described in the text. Note that the galaxy with the highest L_X/L_FIR and L_X/SFR, the stage 7 system NGC 1700, is not plotted in the bottom panel since no UV data are available. In all panels, galaxies containing a Seyfert nucleus are circled in red. The filled blue diamonds are the median values for each stage, slightly offset to the left. The error bars plotted on the median values are the semi-interquartile range, equal to half the difference between the 75th percentile and the 25th percentile. Upper limits above the median were not included in calculating the median.
