Notes

The proposed 10 deg cone fundamentals are based on the CIE XYZ 1964 10-deg color matching functions.

From Stockman, MacLeod and Johnson (1993).

    Columns 2, 3, and 4: logarithms of proposed cone sensitivities based on the ,  and  10-deg CMFs of the CIE 1964 supplementary standard observer, derived from the following transformations, and adapted for small field application through the corrections described below:

  

 

  (λ≤ 525nm) 

   

   The S-cone sensitivities have been extended at λ > 520 nm by using the following function:

  (where λ is the wavelength in nm).
