Average reduced excess surface density profiles of massive CAMIRA clusters as a function of distance from the lens centre. The lengths and densities are rescaled by over-density units. The vertical error bars represent the square root of the diagonal elements of the total uncertainty covariance matrix, including statistical and LSS noise. The profiles are coded by colour and style according to the cluster redshifts, as in the legend, and they are horizontally shifted by 2% along the abscissa for clarity.
