Marginalised constraints on dynamical dark energy in the w₀, w_a parametrisation, Eq. (3). The black contour contains all cosmic shear probes considered in this work, and the red contour is independent of the CMB. The blue and green contours differ only in that the blue one excludes the DESI DR2 BAO. In purple, the Pantheon+ SN sample has been added. The dashed lines mark the ΛCDM values.
