Notes. Comparable summary statistics for the KiDS-1000-v1 catalogue can be found in Table 1 of A21. We note that the differences in summary statistics between our work and A21 stem from both the updated lensfit code and the enhanced redshift calibration outlined in vdB22. The effective number density neff and the ellipticity dispersion per ellipticity component σϵ, i are calculated using the formulae provided in Appendix C of Joachimi et al. (2021). The neff values in this table are derived from an effective area of 777.4 sq. deg. in the CCD pixel frame, making them directly comparable to the values in Table 1 of A21. The correlated Gaussian redshift priors are based on the differences between the estimated and true redshifts, δz = zest − ztrue, as reported in vdB22. The priors are denoted as μi ± σi, where μi represents the mean shift and σi corresponds to the square root of the covariance matrix’s diagonal elements. The mraw results are derived from idealised constant shear simulations, while the mfinal results, our fiducial outcomes, include corrections for the shear-interplay effect and PSF modelling bias. Statistical uncertainties, determined by the simulation volume, are directly computed from the fiducial simulations and denoted as σm.
