Plots for M_3.3′ = 4.34 × 10¹⁴   M_⊙ and M_30′′ ≈ 1.9 × 10¹⁴   M_⊙. Overfitting case. It shows the solution obtained with the BGA when the method is forced to find a nearly exact solution to the problem (ϵ = 2 × 10^-15). The density profile inside the core radius does not follow the profile of the input NFW cluster. Different density peaks and dips can be seen around the center of the FOV. Darker areas correspond to higher masses.
