Effect of the redshift bin mismatch on the amplitude of cross-correlation. (a) Deviation in the amplitude of cross correlation estimated from the DESI-LIS galaxy catalogue with and without leakage correction from its true value (A = 1) in terms of the standard deviation of the amplitude. (b) Comparison of redshift-bin-mismatch-corrected amplitudes from cross correlation with MV, SZ-deproj, and TT CMB lensing convergence maps.
