##' Spectral Locus for the 1931 CIE chromaticity diagram
##'
##' 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.
##'
##' @seealso \code{\link{plotCIEchrom}} for examples of this data in use.
