Detailed Description

Test routine for spin-modulted inspiral waveform generation code.

Sathyaprakash, B. S.

First set the InspiralTemplate structure (example given below). Then call the function LALInspiralWaveLength (&status, &n, params) to measure the length n of the array required. Then call the function LALInspiralWave(&status, signal1, params); to generate the wave, which will be returned in signal. Example values of the parameters that can be set (with options in brackets):

params.OmegaS = 0.;     (Unknown 3PN parameter in energy shown to be zero by DJS)
params.ieta=1;          (1 for comparable masses model, 0 for test mass model)
params.mass1=1.4;       (masses of the component stars in solar masses)
params.mass2=1.4;
params.startTime=0.0;   (in sec. Defined so that the instantaneous GW frequency
is params.fLower at params.startTime)
params.startPhase=0.0;  (0 to LAL_PI_2)
params.fLower=40.0;     (in Hz)
params.fCutoff=1000.0;  (in Hz)
params.tSampling=4000.; (in Hz; should be larger than 2*fCutoff or 2*flso,
whichever is smaller)
params.signalAmplitude=1.0;
params.nStartPad=0;     (number of leading zero bins)
params.nEndPad=0;       (number of trailing zero bins)
params.approximant=SpinTaylorT3;
params.order=twoPN;     (also newtonian, onePN, oneAndHalfPN, twoPN,
twoAndHalfPN, threePN, threeAndHalfPN)
params.massChoice=m1Andm2; (also t0t2, t0t3, t0t4, totalMassAndEta,totalMassAndMu)
params.Theta = 0.;
params.distance = 1.e8 * LAL_PC_SI/LAL_C_SI; (distance in sec)
params.sourceTheta = LAL_PI/6.L;   (Source co-latitute)
params.sourcePhi = LAL_PI/6.L;   (Source azimuth)
 
mass1Sq = pow(params.mass1*LAL_MTSUN_SI,2.L); (mass of the 1st body in sec.)
mass2Sq = pow(params.mass2*LAL_MTSUN_SI,2.L); (mass of the 2nd body in sec.)
spin1Frac = 0.9;        (spin of body 1 in units of its mass)
spin2Frac = 0.3;        (spin of body 2 in units of its mass)
 
params.orbitTheta0 = LAL_PI_2/3.; (initial co-latitute orientation of the orbit)
params.orbitPhi0 = LAL_PI/6.; (initial azimuth orientation of the orbit)
 
(spin of body 1)
params.spin1[0] =  mass1Sq * spin1Frac * sin(spin1Theta) * cos(spin1Phi);
params.spin1[1] =  mass1Sq * spin1Frac * sin(spin1Theta) * sin(spin1Phi);
params.spin1[2] =  mass1Sq * spin1Frac * cos(spin1Theta);
 
(spin of body 2)
params.spin2[0] =  mass2Sq * spin2Frac * sin(spin2Theta) * cos(spin2Phi);
params.spin2[1] =  mass2Sq * spin2Frac * sin(spin2Theta) * sin(spin2Phi);
params.spin2[2] =  mass2Sq * spin2Frac * cos(spin2Theta);
