PIWebb-FitFunc
Model of photosynthesis vs. irradiance curve by Webb
Number: 2
Names: Pm, alpha
Meanings: Pm = photosynthetic capacity, alpha = photosynthetic efficiency
Lower Bounds: Pm > 0, alpha > 0
Upper Bounds: none
Refer to the curve in Sample Curve section:
Half-saturation constant: Ik = ln(2)*Pm/alpha
