S/N and rms maps overlaid with mass contours. Left: mass reconstruction S/N map obtained from 1000 bootstrapped convergence maps. NW_E and NW_W were detected at the 3.3σ and 3.4σ levels, respectively, whereas SE_N and SE_S were detected at the 4.2σ and 4.7σ levels. Right: mass reconstruction uncertainty map. The values represent the standard deviation from the 1000 bootstrap realizations.
