#' @title Hypothetical growth data for testing seasonal age models.
#'
#' @description Hypothetical lengths at seasonal ages. These data are useful for testing growth related functions (e.g., \code{\link{findGrowthStarts}}) as they were generated from known growth functions (e.g., von Bertalanffy) with some random error and are, thus, \dQuote{as good as it gets} for testing.
