Posterior contours from five different mock data vectors given the anisotropic systematics model within KiDS-SBI over the prior space shown in Table 2. Each data realisation assumes the same input parameters (as given by the black line and shown in Table E.1) while varying the random seeds of the underlying matter fields, galaxy positions, intrinsic galaxy shapes, and shear biases. The posteriors shown in Fig. D.2,14, 15, and 16 are based on the 3817 noise realisation.
