Linear energy CIE xyz colour matching function (CMF) 2 deg data

A dataset containing wavelengths at a 1 nm interval (390 nm to 830 nm) and the corresponding x, y, and z 2 degrees CMF values. Derived from proposed CIE 2006 standard. Original data from http://www.cvrl.org/ downloaded on 2014-04-29 The variables are as follows:

• w.length (nm)

• x

• y

• z

Usage

ciexyzCMF2.spct

Format

A chroma_spct object with 441 rows and 4 variables

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.
