Best fits of the averaged stacked tunnel voids tangential shear profiles, γ_t(r_p), measured in ΛCDM cosmology adopting three different parametric functions. The data are derived as the mean of the 256 ΛCDM mock light cones and represented with black markers having error bars computed as specified in Sect. 5.2. The first two models considered are derived from the line-of-sight integration of two 3D void density profile functions: HSW (red dashed line) and HT (green dotted line). The last one is the new formula developed in this work for WL tunnel voids (blue solid line), reported in Eq. (34). The shaded area, in some cases barely visible, represents the 1σ uncertainty associated with each fit.
