Our analysis of the experimental results takes into account the two gap nature of the superconducting state and indicates larger intraband diffusivity in the three-dimensional (3D) $\\pi$ band compared to that in the two-dimensional (2D) $\\sigma$ band. Direct comparison of our results with those reported previously for single crystals indicates that larger intraband scattering in the 3D $\\pi$ band leads to an increase of $\\lambda$.
