Spectral Locus for the 1931 CIE chromaticity diagram
Description
This data set gives wavelengths every 1.0 nm, along with the associated CIE xyz values for the spectral locus of the 1931 CIE chromaticity diagram. They are called xyz values here as they are called that in the original source, but they are also known as xyY or XYZ values.
Usage
CIExyz
Format
A data frame with 4400 observations each with the following 4 variables:
- wavelength
wavelength in nm
- x
x values
- y
y values
- z
z values
