The SNR (top) and SNR_diag (bottom) for the joint clustering and weak-lensing data vector plotted for the jackknife shrinkage in comparison to DICES with N_JK = 74. See Fig. 10 for details on the plot layout. To balance the contributions from clustering and weak lensing we limit all clustering auto and cross angular power spectra to 10 ≤ ℓ ≤ 80. Replacing the standard deviations with the debiased jackknife diagonals improves SNR_diag but biases SNR slightly high. This illustrates the bias is caused due to biases in the estimate of the correlation matrix.
