#' @format A data frame with 6 rows and 7 variables:
#' \describe{
#'   \item{atom}{element name}
#'   \item{ab1}{abundance of the first isotope, as a frequency}

#'   \item{ab3}{abundance of the third isotope, as a frequency}
#'   \item{mass1}{atomic mass of the first isotope, in ma/Da}
#'   \item{mass2}{atomic mass of the second isotope, in ma/Da}
#'   \item{mass3}{atomic mass of the third isotope, in ma/Da}
