Note 1 to entry: The CIE 1964 standard colorimetric system is applicable to centrally-viewed fields of angular subtense greater than about 4° (0,07 rad).
Note 2 to entry: When the CIE 1964 standard colorimetric system is used, all symbols that represent colorimetric measures are distinguished by use of the subscript 10.
Note 3 to entry: See also CIE 15
Note 4 to entry: This entry was numbered 845-03-29 in IEC 60050-845:1987.
