Notes. Properties are taken from the COSMOS X-ray group catalog (Gozaliasl et al. 2019) and the results of Kettula et al. (2013). For details on the derivation of the presented parameters, see the corresponding papers. Presented values are rescaled to the cosmology we use in this paper (if needed).
