Mass profile of the lens models A, B, and C. Red curves correspond to the radial profiles when the center is the north BCG, while the blue curves correspond to the profiles centered in the south BCG. The black lines is the same NFW model from Diego et al. (2018a) with concentration of c = 2 and a virial radius of R₂₀₀ = 3 Mpc. The profiles around the north and south BCG are remarkably similar, suggesting a mass ratio of 1:1 for the two subgroups.
