CIE D65 illuminant data
Description
A dataset containing wavelengths at a 5 nm interval (300 nm to 830 nm) and the corresponding spectral energy irradiance normalized to 1 at 560 nm. Spectrum approximates the midday solar spectrum at middle latitude as 'corresponds' to the white point of a black body a 6504 K. Original data from CIE downloaded on 2024-11-30 The variables are as follows:
