CIE Photometric and Colorimetric Tables
This disc contains files tabulating the CIE Colorimetric Illuminants and Colorimetric Observers, as well as the CIE Spectral Luminous Efficiency for Scotopic Vision and the CIE 1988 2 degree Spectral Luminous Efficiency Function for Photopic Vision (see Publication CIE 86-1990). Every file starts with a text line containing information on the file. Then the data are presented.
The data on this disc supplement the standards ISO 11664-1:2007(E)/CIE S 014-1/E:2006 and ISO 11664-2:2007(E)/CIE S 014-2/E:2006. They contain the data of the tables on pp. 7-28 in ISO 11664-1:2007(E)/CIE S 014-1/E:2006 and on pp. 7-12 in ISO 11664-2:2007(E)/CIE S 014-2/E:2006.
V'(lambda) values are included from ISO 23539:2005(E)/CIE S 010/E:2004 (pp. 10-13).
VM(lambda) values in the range of 380 nm to 460 nm are taken from CIE 86-1990, in the range of 461 nm to 780 nm from ISO 11664-1:2007(E)/CIE S 014-1/E:2006, with according rounding.
