#' Step 1/2 scenario data as distributed with the FOCUS Step 1/2 calculator

#' The data were extracted from the scenario.txt file using the R code shown below.
#' The text file is not included in the package as its licence is not clear.

#' @name FOCUS_Step_12_scenarios
#' @docType data
#' @format A list containing the scenario names in a character vector called 'names',
#'   the drift percentiles in a matrix called 'drift', interception percentages in
#'   a matrix called 'interception' and the runoff/drainage percentages for Step 2
#'   calculations in a matrix called 'rd'.
