This is the same type of comparison as shown in Figure A1; however, the blue-filled shapes are the X-ray contours at a level of 7 × 10⁻⁹ counts s⁻¹ cm⁻² pixel⁻¹ also shown in previous figures as the interior contours, and they trace the densest parts of the cloud. The OPs with X-ray being the primary data set are shown in blue in the lower left of each panel, and the percentages with H₂CO being the primary data set are shown in pink in the lower right of each panel. These percentages for the dense cores of the cloud are, on average, 27% higher than the percentages shown in Figure A1, which makes sense as H₂CO is a dense gas tracer.
