\title{Example passive acoustic telemetry detections dataset}
\format{
A dataframe with 39,242 observations and 9 variables:
\describe{
  \item{individual_id}{A unique identifier of the individual that was detected (see \code{\link{dat_ids}}).}
  \item{transmitter_id}{The acoustic transmitter that was detected (see \code{\link{dat_ids}}).}
  \item{index}{An integer individual-specific cumulative detection index.}
  \item{timestamp}{A POSIXct object which defines the time of each observation.}
  \item{receiver_id}{A unique identifier of the receiver at which the individual was detected (see \code{\link{dat_moorings}}).}
  \item{receiver}{The receiver at which the individual was detected (see \code{\link{dat_moorings}}).}
  \item{receiver_long}{The longitude of the receiver at which the individual was detected (see \code{\link{dat_moorings}}).}
  \item{receiver_lat}{The latitude of the receiver at which the individual was detected (see \code{\link{dat_moorings}}).}
  \item{receiver_depth}{The depth of the receiver at which the individual was detected (see \code{\link{dat_moorings}}).}

\description{
A dataset containing a sample of processed flapper skate (\emph{Dipturus intermedius}) detection time series. Data are arranged by \code{individual_id}, \code{timestamp} and then \code{receiver_id} (see below).
}
\details{
Time stamps are expressed to the nearest two minutes. `Duplicate' detections (of the same individual at the same receiver in the same time step) are excluded. This supports the implementation of the acoustic-container (AC) and acoustic-container depth-contour (ACDC) algorithms (see \code{\link[flapper]{ac}} and \code{\link[flapper]{acdc}}).
