Comparison of the errors on the marginalised (light grey) and unmarginalised (dark grey) cosmological parameters. Top panels: we compare seven WL codes for the flat w0, wa cosmology, using the “TakaBird” recipe for the non-linear power spectrum and a maximum multipole of max = 1500 (pessimistic cut, top left panel) or max = 5000 (optimistic cut, top right panel). This is case 3 in Table 8. Bottom panels: we compare three WL codes (the ones available for a non-flat geometry that include γ), for a γ, w0, wa cosmology, using the “TakaBird” non-linear recipe for the power spectrum and a maximum multipole of max = 1500 (pessimistic cut, bottom left panel) and a maximum multipole of max = 5000 (optimistic cut, bottom right panel). This is case 6 in Table 8.
