摘要：Owing to an issue in the fitting program XSPEC version 12.8.2 1 , the correlations of metallicity with redshift and temperature in Hofmann et al. (2016) need to be revised. The bug caused nor- malisation (η) and metallicity (Z) in the apec model to be a fac- tor of ∼ (1 + z) too low (z, redshift of the source).
