Cosmological constraints from the GCph analysis neglecting magnification (blue contours), including magnification and assuming a perfect knowledge of the local count slope (red contours), and marginalising over the local count slope parameters with a 10% prior (yellow contours). The results reported here refer to our baseline cosmology, that is, the w₀ w_aCDM model. The contour plot was generated using the Python library CosmicFish (Raveri et al. 2016). Dark and light contours refer to the 1σ and 2σ confidence level, respectively.
