Left: detection maps showing the percentage of recovered injected signals as a function of period and semi-amplitude for the narrow and wide BERV coverages. Middle: same detection tests after applying the wapiti correction. Right: difference between the recovered and injected K values (ΔK = K_out − K_in) at 1 m s⁻¹, with the shaded area indicating one standard deviation. The color bar indicates the detection rate in percent.
