15. For some junctions we could obtain better fits by using a higher temperature. This is most likely due to the fact that we did not explicitly introduce any gap smearing, as is customary in superconducting tunneling [i.e., R.C. Dynes et. al Phys. Rev. Lett. 53, 2437 (1984)]. Fitting with an increased temperature is to a large extent equivalent to an additional gap smearing. We emphasize that even when increasing the temperature parameter impoves the quality of the fits, it hardly changes the resulting spin polarization.
