Details
Equation:
rT = Rm * e^{-\frac{1}{2} * (\frac{T - Tmax}{To})^{2}}
and
rT = Rm * e^{-\frac{1}{2} * (\frac{T - Tmax}{T1})^{2}}
where rT is the development rate, T the temperature, Rm the maximum development rate, Tmax the optimum temperature, and To and T1 the shape parameter giving the spread of the curve.
