Fisher matrix forecast for KiDS-1000. The SEK COSEBIs (blue) are compared with (pink), showing that they contain the same level of information about the model parameters, S₈ and A_IA. All other parameters, listed in Table 1, are fixed to their fiducial values. The fact that one sees only one ellipse is because both methods give the same Fisher ellipses, which thus lie on top of each other, as expected. This figure is made with CHAINCONSUMER (Hinton 2016).
