Euclid DR1 forecast, where we used a flamingofied reference data vector (see Sect. 5.5) estimated from the fiducial baryon description of the FLAMINGO simulations with eight light cones of the 2.8 Gpc box. The stated constraints correspond to the joint analysis of second- and third-order statistics. The posteriors are the same as those used in Fig. 6, meaning we marginalised over all BCM parameters. The stated constraints correspond to the joint analysis of second- and third-order statistics (blue contours). The grey dashed line indicates the underlying D3A cosmology.
