#' McCree's action spectra for whole-leaf photosynthesis.
#'
#' @description The 'classical' action spectra of K. J. McCree (1972) for
#'   \emph{Amaranthus edulis} Speg. var. UCD 1966 and \emph{Avena sativa} L.
#'   var. Coronado are included in this data set. Response is net \eqn{CO_2}
#'   uptake measured on leaf sections umder monochromatic light. The light
#'   source used was a xenon-arc lamp fitted with a monochromator. Irradiance
#'   was in the range 10 to 15 \eqn{W m^{-2}}.
