Ridl, Jethro Venn (2017): End-to-end cluster cosmology: constraining cosmological parameters with X-ray selected galaxy clusters. Dissertation, LMU München: Fakultät für Physik
... To model the bias, we split the clusters into two populations, one within 5 0 of the pointing centre (assuming that all pointed clusters are within 5 0 ) and the other between 5 0 and 13 0 . Clerc et al. (2012b) showed ...
