Projected response coefficients for the WL and GCph probes and their cross-correlation for the central redshift bin (0.8 ≲ z ≲ 0.9). The shape and amplitude of the functions for different redshift pairs are analogous. For WL, the baryon acoustic oscillation wiggles are smoothed out by the projection, because the kernels are larger than the GCph ones. The different amplitude of the response is one of the main factors governing the severity of SSC.
