Gaussian curve is a curve with a classic bell shape that has a maximum around the average of the measured values and can be more or less narrow depending on the dispersion of the values around the average.

Indeed, by applying the fluctuation-dissipation theorem and modeling the out-of-phase component C" as a Gaussian curve (supposing temperature variable and frequency constant), [delta]T corresponds to the standard deviation of this Gaussian curve [52] and [T.sub.[alpha]] is its maximum.
