Marginal posteriors using band powers in the internal consistency test that isolates all bin combinations involving the second tomographic bin. The test duplicates the sampling parameters (with fixed δ_z) and assigns them to the two parts of the data vector. The orange contours refer to the split including the second bin and all its cross-correlations, while the blue ones present the constraints from the remainder of the redshift bins (and their cross-correlations). The cross-covariance between the two parts of the data are included via the data covariance matrix. Other divisions of the data show much more consistent results.
