CIE 2007 "physiologically-relevant" functions (to 8 dp)

See: CIE (2007). Fundamental chromaticity diagram with physiological axes – Parts 1 and 2. Technical Report 170-1. Vienna: Central Bureau of the Commission Internationale de l' Éclairage. These functions are the same as the CVRL functions, but to 8 decimal places. The data are provided either as ascii csv (comma separated values) files, as ascii xml (extensible markup language) files, as html tables, which appear in your browser window, or as dynamic graphical plots. Select the data format, the data stepsize and the data units and click the "Submit" button. For further details and references click .

Please note the functions linked to this page are tabulated to 8 dp, in contrast to the standard functions, which are tabulated to 5 dp. These are provided to facilitate calculations. Versions to 5 dp can be found here.
