\subsubsection*{Description}

The function \texttt{LALInspiralPhiofVIntegrandIn} calculates the quantity $v^{3} E^{\prime}(v)/\mathcal{F}(v)$.

\subsubsection*{Algorithm}


\subsubsection*{Uses}

This function calls {\tt dEnergy} and {\tt flux} functions that are defined in the 
{\tt expnFunc} structure  and represent $E^{\prime}(v)$ and $\mathcal{F}(v)$, respectively,
and pointed to the appropriate PN functions with a call to \texttt{LALInspiralChooseModel.}
