1D and 2D marginal posteriors for CFIS-P3, with the residual multiplicative shear bias added. The 2D inner and outer contours show the 68% and 95.5% credible region, respectively. Ω_m shifts by −0.01, which corresponds to −0.2σ when the calibration goes from global (blue contour) to local on 1 deg² (green contour). When Δm is added (red contour), Ω_m shifts by −0.024, which corresponds to −0.5σ with respect to the global calibration.
