#' @title Compile JAGS data

#' @description Compile data into format for the JAGS total escapement model
#'
#' @author Kevin See
#'
#' @param lgr_weekly dataframe containing weekly summaries of window counts and trap data. Part of what is returned by \code{summSTADEM}.
#' @param sthd_B_run should numbers of B run steelhead be incorporated? These are defined as wild steelhead greater than 780mm in length. Default is \code{FALSE}.
#' @param hw_type what criteria is used to determine hatchery vs. wild? \code{Morph} uses the morphilogical call made at the trap. \code{PBT} uses the genetic information gleaned from parental based tagging.
#' @param wild_tags Should only wild PIT tags be used to estimate daytime passage and re-ascension rates? Default is \code{FALSE}.
