Notes

Mean data from Pitt (1935). From Table 4(5.14.2) of Wyszecki & Stiles (1982).

Though a standard data set, these data should be used with some caution. First, they may be subject to a wavelength-dependent calibration error. Second, since they were obtained by brightness matching, they may be influenced by short-wavelength sensitive cones at short wavelengths
