Differences in log L_X/L_bol between eROSITA and Chandra (orange), and between eROSITA and XMM-Newton (blue). The differences are in the sense of (Other – eROSITA). The dotted lines show the mean offsets between the datasets. These offset values were used to adjust the prior data to the eROSITA level when necessary for cross-comparisons. Data points outlined in black indicate cluster members.
