Correlation coefficient matrix for the angular galaxy clustering correlation function w, the galaxy-galaxy lensing band power 𝒞_nϵ, and the cosmic shear band power 𝒞_E calculated over the full BOSS and KiDS-1000 footprints. The upper triangle shows the correlation matrix as calculated from the mocks; the lower triangle indicates correlation coefficients above ±5%. The black rectangles highlight the cross-correlations between galaxy clustering and weak lensing statistics. These are negligible, with few elements fluctuating above the 5% threshold.
