We performed a basic analysis of the raw data from the flight device (SN 011-018)  separations at  ambient, cold vacuum (-20°C), thermal balance and thermal cycling cases. From these data, we  determined the mean, standard deviation and two-sigma data, for time to separate, delta-T, and power required to separate.    The two-sigma time to separate is calculated as follows:  T 2σ = Mean + (2 * σ ) where T2σ is the 2 sigma  time to separate, Mean  is the arithmetic mean of the times to separate, and σ is the standard deviation  between the times to separate.
