 In order to build a surrogate also for the robustified Levenberg-Marquardt, introduce
 ``α = 1 - $(_tex(:sqrt, "1 + 2 $(_tex(:frac, "ρ''(p)", "ρ'(p)"))$(_tex(:norm, "F(p)"; index = "2"))^2"))``

 ```math
 C = $(_tex(:sqrt, "ρ'(p)"))(I-αP), $(_tex(:qquad)) P = $(_tex(:frac, "F(p)F(p)^" * _tex(:rm, "T"), _tex(:norm, "F(p)"; index = "2") * "^2")),

 These two can be accessed with [`get_vector_field`](@ref) for ``y`` and [`get_linear_operator`](@ref) for ``$(_tex(:Cal, "L"))``,
 respectively.
 For technical details on the scaling using ``α``, especially how the `threshold` and `mode`
