Dynes ansatz is a broadly utilized procedure to extract the superconducting energy gap from the tunnelling differential conductance, a quantity that is measured by scanning tunnelling microscopy (STM) techniques. In this letter we investigate the limit of applicability of this ansatz in nano-scale superconductors and propose a generalization that permits to study thermal and quantum fluctuations in STM experiments.
