#' Between source covariance matrix of eight trace copper wire chemical
#' concentrations.
#'
#' A covariance matrix providing the estimated variances and covariances of
#' the mean vector of eight chemical concentrations between multiple unique
#' sources. This covariance matrix is used for each component in a two component
#' Gaussian mixture model describing the mean chemical
#' concentrations of samples with different sources.
#'
#' @format An 8 x 8 matrix.
