“Ratkowsky function”

Finally if the “Ratkowsky function” is chosen, the temperature response function is calculated differently depending on the temperature:

1.  T > t_max

2.  t_min < T < t_max
                                    (5.85)

3.  T < t_min

where t_min and t_max are parameters. See viewing function Common temperature response function - Ratkowsky function.
