(a) Scatter plot in the ∑𝑚_𝜈−𝑁_eff plane with points colored by the value of the 𝐴_𝐿 parameter (second column of Table 3). (b) 68% and 95% c.l. 2D marginalized posterior in the plane ∑𝑚_𝜈−𝑁_eff; blue contours refer to the case with a varying lensing amplitude (second column of Table 3) and red contours illustrate the 𝐴_𝐿=1 case (first column of Table 3).
