Table T.9: CIE 1988 Modified Two-Degree Spectral Lumnous Efficiency Function for Photopic Vision


NOTE: This table’s section number was changed in RP-16-17 Addendum 1.  The previous section number was 13.9.

Note: Information in this table was obtained from Appendix of CIE 86 (1990), CIE 1988 2º Spectral Luminous Efficiency Function for Photopic Vision.

Note: This function is identical to V(λ) at wavelengths of 460 nm and longer.
