\title{Apply Storage Flux Correction}
\usage{
add_st(flux, st, stp = NULL, name_out = "-")
}
\arguments{
\item{flux}{A numeric vector with flux values.}

\item{st}{A numeric vector with storage computed using discrete
(one point) approach.}

\item{stp}{A numeric vector with storage computed using
profile measurement of CO2.}

\item{name_out}{A character string providing \code{varnames} value of the
output.}
}
\value{
A vector with attributes \code{varnames} and \code{units} is
  produced. \code{varnames} value is set by \code{name_out} argument.
  \code{units} value is extracted from \code{flux} vector by
  \code{\link{units}} or set to default \code{"-"}.
}
\description{
Correction of matter or energy flux (\code{flux}) with storage computed using
discrete (one point) approach (\code{st}) or profile measurement of CO2
concentration (\code{stp}).
}
\details{
If both storage estimates are available, \code{stp} takes priority. If both
\code{st} and \code{stp} estimates are \code{NA}, original flux value is
kept. \code{flux}, \code{st} and \code{stp} (if not NULL) must have the same
length.
