A dataset containing wavelengths at a 1 nm interval (390 nm to 830 nm) and the corresponding x, y, and z chromaticity coordinates. According to proposed CIE 2006 standard. Original data from http://www.cvrl.org/ downloaded on 2014-04-28 The variables are as follows:
w.length (nm)
x
y
z
Note
These data are not from the official CIE on-line distribution but are retained for backwards compatibility. It is recommended to download the latest version from https://cie.co.at/data-tables.
