Make a monotone Hermite spline function (Fritsch and Carlson, 1980) fitted on Drinnan et al. (1995)
data. This function is given as a parameter in the coffee parameter file to be further used in the model as
Bud_T_correction()
so the user can modify the function and give it as input.

As temperature increases, the number of nodes on coffee increases due to increased vegetative
growth (see CN()
), but the number of inflorescences per node, and the number of flowers per inflorescence
decrease. This function fits a function that return itself a temperature correction coefficient that is fitted
on the quite unique dataset of Drinnan and Menzel (1995). The correction coefficient is applied in DynACof to the
number of buds that break dormancy (less buds break dormancy with increasing T).
