Popis: The analysis of SIGNE experiment data shows that the theoretical laws we have tested assuming a single component continuum probably do not describe the real phenomenon of gamma emission and that there is a very fast spectral evolution, possibly on timescales down to 16 ms. Moreover we have not found a universal value of a for the relation F = (kT) α /3/, but rather a gradual decrease of the spectral hardness index during pulses.
