Abstract

Tristimulus integrals are approximated by summation equations. Now, interesting question is what should the wavelength interval be to obtain accurate tristimulus values? CIE recommends to do summation with 1 or 5 nm intervals. For dense intervals ASTM weighting sets are recommended to use. In that method weighting sets are calculated by Lagrange interpolation.
