KSWS1-KLWS represent the weights of the relative contribution of each cone mechanism to spectral sensitivity used in the multiple-cone mechanism model. Weights can be positive (nonopponent) or negative (opponent). The spectral ranges listed in this table represent discernible peaks (or cone mechanism) in the spectral sensitivity curves, and each peak was fitted by the multiple cone mechanism model.
