\title{Expected Signal Given Observed Foreground Under Normal+Exp Model}
\description{
Adjust foreground intensities for observed background using Normal+Exp Model.
This function is called by \code{backgroundCorrect} and is not normally called directly by the user.
}
\usage{
normexp.signal(par, x)
}
\arguments{
  \item{par}{numeric vector containing the parameters of the Normal+Exp distribution, see \code{\link{normexp.fit}} for details.}
  \item{x}{numeric vector of (background corrected) intensities}
}
\details{
In general the vector \code{normmean} is computed conditional on background at each spot.
}
\value{
Numeric vector containing adjusted intensities.
}
