Comparison of 68% C.L.’s obtained from the Fisher analysis for ΛCDM (left) and w₀w_aCDM (right) with no lensing magnification (blue), with lensing magnification and the local count slope fixed (orange) in each redshift bin, and with magnification and local count slope marginalised (green). We note that for w_a, we do not divide by the fiducial as it is zero, and instead we show the absolute error. For the corresponding data, see Table 4.
