Notes

Values of $\bar{x} (λ)$ , $\bar{y} (λ)$ and $\bar{z} (λ)$ are defined in the CIE 1931 standard colorimetric system (2° observer) -- applicable to fields of observation of angular opening from 1° to 4°.

Les valeurs de $\bar{x} (λ)$ , $\bar{y} (λ)$ et $\bar{z} (λ)$ sont définies dans le système de référence colorimétrique CIE 1931 (observateur 2°) -- applicable aux champs d'observation d'étendue angulaire comprise entre 1° et 4°.
