\usage{
correct_PMTLinearity(object, PMT_pulse_pair_resolution = NULL)
}
\arguments{
\item{object}{\linkS4class{RLum.Analysis} \linkS4class{RLum.Data.Curve} (\strong{required}):
object with records to correct; can be a \link{list} of such objects}

\item{PMT_pulse_pair_resolution}{\link{numeric} (\emph{with default}): pulse-pair resolution
in ns. Values can be found on the PMT datasheets. If \code{NULL} nothing is done.}
}
\value{
Returns the same type of object type as \code{object}.
}
\description{
Correct dead-time (also linearity) of PMT counts to avoid saturation effects, depending
on pulse-pair-resolution of individual PMTs.
}
\details{
We correct for count linearity using a well-known formula that can be
found for example in the Hamamatsu Photomultiplier handbook
(Hamamatsu Photonics K.K., 2017):

\deqn{N = \frac{M}{1 - M*t}}

where \eqn{N} (in s\eqn{^{-1}}) is the true count rate, \eqn{M} (in s\eqn{^{-1}}) the measured count rate,
and \eqn{t} (in s) the pulse pair resolution.
}
\note{
This function is an adaptation of core from the R package
'OSLdecomposition'.
}
\examples{
o <- set_RLum("RLum.Data.Curve")
correct_PMTLinearity(o, PMT_pulse_pair_resolution = 10)
