Stacked bar chart of cosmological parameter biases resulting from the studied higher-order effects, for the flat ΛCDM case (left) of Table 5, and the flat w₀w_aCDM case (right) of Table 6. The non-flat Universe term is not shown here, due to the different cosmology. Biases are presented here as a fraction of the 1σ parameter uncertainty. A bias is non-negligble if its absolute value reaches or exceeds 0.25σ. ‘RS’ denotes the reduced shear correction, ‘SLC’ is the source-lens clustering term, ‘MB’ is the magnification bias correction, ‘SO’ is the two-point source obscuration correction, ‘SO-MB’ and ‘SO-SLC’ are the source obscuration-magnification bias and source-lens clustering cross terms respectively, and ‘LU’ is the local Universe correction The segments with the dashed outlines show the total parameter biases from these corrections for each parameter.
