The fitted results of the empirical data using the four photosynthetic light response models (A EM; B RHM; C NHM; D MRHM) for a representative dataset selected from 42 datasets. Data points represent observations; the curves signify predicted photosynthetic light response curves. Letters a, Amax, Rd, θ, β, and γ with hats represent the estimated least-squares values of the parameters of the corresponding photosynthetic light response model in each panel; n represents the number of observations; RMSE represents the root-mean-square error.
