#' Fin Ray Analysis of San Francisco Estuary-based White Sturgeon.
#'
#' @description A dataset with 100 observations & variables \code{lencap},
#'    \code{radcap}, and \code{anu<number>}, where number is 1-->10. These
#'    data represent required format for using \code{BackCalcLength()}. Data
#'    are from White Sturgeon fin ray sampling & ageing.
#'
#' @format A data frame with 100 observations and 12 variables:
#' \describe{
#'   \item{lencap}{length at capture (in this case fork length)}
#'   \item{radcap}{radius at capture}
#'   \item{anu1}{annulus at age-1}
#'   \item{anu2}{annulus at age-2}
#'   \item{anu3}{annulus at age-3}
#'   \item{anu4}{annulus at age-4}
#'   \item{anu5}{annulus at age-5}
#'   \item{anu6}{annulus at age-6}
#'   \item{anu7}{annulus at age-7}
#'   \item{anu8}{annulus at age-8}
#'   \item{anu9}{annulus at age-9}
#'   \item{anu10}{annulus at age-10}
#' }
#'
#' @details These data establish back-calculated length at age. Data are
#'    real but subsetted here for ease of demonstration.
