\HeaderA{normexp.signal}{Expected Signal Given Observed Foreground Under Normal+Exp Model}{normexp.signal}
\keyword{models}{normexp.signal}
\begin{Description}\relax
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.
\end{Description}
\begin{Usage}
\begin{verbatim}
normexp.signal(par, x)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{par}] numeric vector containing the parameters of the Normal+Exp distribution, see \code{\LinkA{normexp.fit}{normexp.fit}} for details.
\item[\code{x}] numeric vector of (background corrected) intensities
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
In general the vector \code{normmean} is computed conditional on background at each spot.
\end{Details}
\begin{Value}
Numeric vector containing adjusted intensities.
\end{Value}
