ST-Kinetics and Multi-Wavelength Chlorophyll Fluorometer
Fitting routine for the fast fluorescence O-I1 to determine the functional absorption cross-section of the PS II antennae (Sigma) needed for the determination of PS II-specific electron transport rates
Fitting routine for exponential decay (e.g. QA– reoxidation after a single turnover flash) or rise of a signal with up to three exponentials
Choice of two fitting routines for light curves (determination of cardinal points α, Ik and ETRmax)
