Notes. We report the detection significance in each redshift bin, for the 50%–50% split and the 10%–90% split. The columns labelled with ‘theory covariance’ use the linear covariance described in Sect. 2.3. The columns labelled with ‘JK covariance’ use the numerical covariance estimated with the JK method, as detailed in Sect. 3.6. The ‘combined covariance’ corresponds to the rescaling of the theory covariance matrix by the diagonal elements of the JK covariance.
