Description
Uses the Eilers photosynthesis irradiance curve with an extra parameter allowing for a varying y-intercept. This allows for negative rates of photosynthesis to be modelled.
Usage
1
Eilers_PI_mod(Pmax, Iopt, a, I, c)
Arguments
Pmax
The photosynthetic maxima
Iopt
The optimal light intensity
a
The initial slope of the curve
I
Light
c
The y intercept controlling the height of the curve
