Detailed Description

The code LALInspiralEccentricity generates a time-domain inspiral waveform corresponding to the approximant Eccentricity as outlined PRD 60 for the Newtonian case.

Author

Prototypes

LALInspiralEccentricity()

• signalvec: Output containing the inspiral waveform.
• params: Input containing binary chirp parameters and eccentricity.

LALInspiralEccentricityTemplates()

• signalvec1: Output containing the 0-phase inspiral waveform.
• signalvec2: Output containing the \(\pi/2\)-phase inspiral waveform.
• params: Input containing binary chirp parameters.

Description

LALInspiralEccentricity is called if the user has specified the enum approximant to be either TaylorT1 or PadeT1. LALInspiralEccentricityTemplates is exactly the same as LALInspiralEccentricity, except that it generates two templates one for which the starting phase is params.startPhase and the other for which the phase is params.startPhase + \(\pi/2\).

Algorithm

This code uses a fourth-order Runge-Kutta algorithm to solve the ODEs in Eq. \eqref{eq_ode2}.

Uses

LALInspiralSetup()
LALInspiralChooseModel()
LALInspiralVelocity()
LALInspiralPhasing1()
LALInspiralDerivatives()
LALRungeKutta4()
