Two-dimensional marginalized posterior likelihood contours for f and σ₈ at 0.5 <z < 0.7, showing the impact of the additional galaxy-galaxy lensing constraint on the f−σ₈ degeneracy. The black curve shows the region of constant fσ₈ associated with Planck Collaboration XIII (2016)ΛCDM + GR best-fit, while the combined (f,σ₈) constraint is marked with the star.
