Detailed Description

These modules generate a time-domain chirp waveform of type TaylorT2.

Author: Sathyaprakash, B. S.

Prototypes

XLALInspiralWave2()

output: Output containing the inspiral waveform.
params: Input containing binary chirp parameters.

XLALInspiralWave2Templates()

output1: Output containing the 0-phase inspiral waveform.
output2: Output containing the \(\pi/2\)-phase inspiral waveform.
params: Input containing binary chirp parameters.

Description

XLALInspiralWave2() generates TaylorT2 approximant wherein the phase of the waveform is given as an implicit function of time as in Eq. \eqref{eq_InspiralWavePhase2}. A template is required to be sampled at equal intervals of time. Thus, first of the equations in Eq. \eqref{eq_InspiralWavePhase2} is solved for \(v\) at equally spaced values of the time steps \(t_k\) and the resulting value of \(v_k\) is used in the second equation to obtain the phase \(\phi_k\).

XLALInspiralWave2Templates() is exactly the same as XLALInspiralWave2() except that it generates two waveforms that differ in phase by \(\pi/2.\)
