Chandra and eROSITA luminosities of a sample of SPT-selected galaxy clusters. Luminosities are calculated in the 0.5–2.0 keV rest-frame band within a projected radius of 600 kpc. In this plot, only those clusters with an uncertainty of less than 10% from Chandra and 20% from eROSITA are shown (66 out of83). The median ratio between the values suggests that the eROSITA luminosities are lower than the Chandra ones by around 15%.
