Question investigated
Do the DES, KiDS and HSC weak-lensing mass calibrations used by eROSITA show tension at high redshift?
Test conditions
Compare cross-calibration checks for clusters in common and summaries of lensing-fit quality from DES, HSC and KiDS. Distinguish overall fit problems from discrepancies confined to high redshift.
Result
The summaries examined do not establish a high-redshift-specific discrepancy of at least 3σ. A full hierarchical comparison of the calibrations is still required for a conclusive assessment.
Physical interpretation
The comparison uses published calibration summaries. A poor overall fit in one survey does not by itself demonstrate disagreement between calibrators at high redshift.
