From: Comparison of four light-response models using relative curvature measures of nonlinearity

Assessment of nonlinear behavior of the four photosynthetic light response models (EM, RHM, NHM, and MRHM) at the global level for 42 datasets. \(\:{{\upgamma\:}}_{\text{RMS}}^{N}\) represents root-mean-square intrinsic curvature, \(\:{{\upgamma\:}}_{\text{RMS}}^{T}\) represents root-mean-square parameter-effects curvature, and Kc represents critical curvature. For example, 80.95% represents that there are 80.95% of \(\:{{\upgamma\:}}_{\text{RMS}}^{T}\) values which are smaller than the corresponding Kc among 42 datasets for RHM.
