In this screen users can fit an asymptotic curve to their data by specifying the intercept, initial slope, and asymptote. Adjustments can be made to get the best fit by minimizing the error sum of squares. These parameters can be translated into rates of dark respiration, photochemical efficiency, carbon dioxide conductance, light compensation points, and photosynthetic saturation levels.
