Chandra cluster flux versus the XXL cluster flux, F₆₀. C1 clusters are black circles/crosses/arrows, C2s are yellow circles/crosses/arrows, and C3s are blue circles/crosses/arrows. The crosses are F₆₀ as listed in Col. 4 of Table 2 (i.e. the original flux, not excluding the point sources detected by Chandra). The circles are the F₆₀ minus theflux from any point source detected in the Chandra data that was not previously resolved by XXL data (listed in Col. 6 of Table 2). The solid line is a line of equality. The arrows indicate upper limits on the Chandra cluster flux – the tip of the arrow denotes the upper limit and are plotted against the point source corrected XXL flux. 3XLSS J022059.0-043922 and 3XLSS J022554.3-045059 are not shown on the plot as the Chandra point source flux is greater than F₆₀.
