1D and 2D marginal posteriors for CFIS-P3, with the peak count predictions corrected with different baryonic feedback. The 2D inner and outer contours show the 68% and 95.5% credible region, respectively. The case without baryonic correction (blue) is compared to the three baryonic scenarios: LowAGN (green), Fiducial (red), and HighAGN (pink). Ω_m shifts by +0.027, which corresponds to +0.5σ when the fiducial goes from dark-matter-only to LowAGN correction.
