Left:N(z) used in the fiducial cosmic shear analyses of KiDS-Legacy. Each panel is one tomographic bin whose definition is determined by the grey band in photo-z. The N(z) have been shifted according to the mean bias estimated using our SKiLLS simulations, making each N(z) a correct representation of the effective N(z) that is used in the cosmological analyses. Fiducial biases are provided in Table 1. Right:δz correlation matrix for our fiducial N(z) (δ_z^SOM, lower triangle) and the correlation matrix inferred from our cross correlation N(z) on the data (D_z^CC, upper triangle).
