Top: M_ap(θ₀) (Eq. (34)) as a function of θ₀, for the composite Hernquist+gNFW model (black), for the power law model M1 (blue), and the cored power-law M2 (red). Dashed red (blue) profile shows M_ap(θ₀) for an MST transformed version of the composite model with λ = 0.93 (resp. 0.84). Bottom: ratio of M_ap(θ₀) between the “transformed” models and the composite. The dashed curves correspond to MST-transformed versions of the composite model, and represent the contribution of the MST to M1 and M2. The solid red and blue curves suggest that the remaining of the degeneracy can be associated with an SPT.
