compare the functions - is one more meaningful than the other?
processes
light limitation then light saturation
Pmax and Ek
model name equation in Excel Blackman = MIN(E * Pmax/Ek , Pmax) Hyperbolic tangent = Pmax *TANH(E/ Ek) Saturating Hyperbola = Pmax * E / ( E + Ek) Poisson ( distribution of photons hitting a small target - link)
Ek is sites and E is events per time interval
= Pmax*POISSON(1, Ek/E, TRUE)
