Measurements of the B-mode signals using COSEBIs for the KiDS-1000-v2 catalogue (red points) compared to the KiDS-1000-v1 catalogue (grey points). The error bars originate from the diagonal of an analytical covariance matrix, accounting solely for measurement noise. For the KiDS-1000-v2 catalogue, we re-calculated the covariance using the method introduced by Joachimi et al. (2021), incorporating the updated statistics. The p-values for the KiDS-1000-v2 catalogue, shown in the top-right corner of each panel, were calculated with 20 degrees of freedom, which corresponds to the number of modes used in each correlation.
