The absorption spectra of the long- and medium-wavelength-sensitive cone photopigments were derived by determining the spectra that best accounted for either the individual differences in the Stiles-Burch 10 degrees color matches [Opt. Acta 6, 1 (1959)] or the changes in color matches at high light levels due to photopigment bleaching [Vision Res. 20, 23 (1980)]. The estimates were made by finding the best-fitting coefficients for an 11th-order polynomial function of wavelength, with no requirement that the resulting sensitivities be consistent with the color-matching functions. The estimates are independent of the scaling effects of any inert screening filters and therefore directly reflect the photopigment sensitivities. The spectra implied by the differences in the matches are similar to the absorption spectra of Smith et al. [Vision Res. 16, 1087 (1976)], which were used as initial estimates. However, the peak sensitivity of the required long-wavelength-sensitive pigment is shifted toward slightly longer wavelengths.
通过确定最能解释以下两种情况的光谱，得出了长波和中波敏感视锥色素的吸收光谱：一是斯泰尔斯-伯奇10度颜色匹配中的个体差异[《光学学报》6, 1 (1959)]，二是高光水平下由于色素漂白导致的颜色匹配变化[《视觉研究》20, 23 (1980)]。通过找到波长的11次多项式函数的最佳拟合系数进行估计，不要求所得灵敏度与颜色匹配函数一致。这些估计独立于任何惰性滤光片的缩放效应，因此直接反映了色素的灵敏度。匹配差异所暗示的光谱与史密斯等人[《视觉研究》16, 1087 (1976)]的吸收光谱相似，后者被用作初始估计。然而，所需长波敏感色素的峰值灵敏度向稍长波长方向移动。
