Correlation between the parameters of redshift dependence (R_n, τ, left panel) and among the parameters of mass function (μ, c, γ, middle and right panel). Blue markers correspond to 10 yr of observations with aLIGO; green markers correspond to 1 month of observations with half-ET, and orange markers correspond to 1 month of observations with ET. The red cross in each panel marks the location of the true values that were used to generate the observed catalogue.
