*a*The parameters are defined as follows:*D*_{98}, the*D*value at 98°C;*m*_{98}, the DPA release delay parameter at 98°C (min); Δ_{98}, the DPA release duration parameter at 98°C (expressed in minutes);*Z*, the temperature change that is required to change the*D*value by a factor of 10 (expressed in degrees Celsius);*Z*, the temperature change that is required to change the_{m}*m*value by a factor of 10 (expressed in degrees Celsius);*Z*_{Δ}, the temperature change that is required to change the Δ value by a factor of 10 (expressed in degrees Celsius);*N*_{0}, the number of viable spores at time zero minus the rest population*N*;_{r}*N*, the heat-resistant rest population of the spores;_{r}*F*_{1}, the minimum DPA concentration as measured by the emission of the Tb(DPA)^{+}complex (expressed in relative fluorescence or arbitrary units [AU]);*F*_{2}, the maximum DPA concentration (arbitrary units) with the temperature (in degrees Celsius) in subscript;*A*_{1}, the minimum DPA release (expressed as a percentage);*A*_{2}, the maximum DPA release (expressed as a percentage).
