params (Array, or tilde-delimited string):

containing parameters for the specified waveform type. The format and definition of the parameters depend on the waveform type. For details on a specific waveform, e.g. WNB, do xmakewaveform(‘WNB’).

T (int):

Duration of the waveform. Must have T*fs = integer. Recommend T>=1 for astrophysical waveforms.

T0 (int):

Desired peak time of the waveform, as measured in hrss for (hp.^+hc.^2).^(0.5). Must have 0<T0<T. See “Notes” below for caveats.

fs (int):

Sampling rate of the time series. T*fs must be an

integer.

Returns:
t:

Times at which the waveform is sampled, starting from zero.

hp:

Plus polarization waveform [strain].

hc:

Cross polarization waveform [strain].

hb:

Breathing (scalar) polarization waveform [strain]. Identically zero for all waveform types unless explicitly stated otherwise.

Notes:

The waveform is interpolated so that the RSS-weighted center time, [int dt t (hp.^+hc.^2+hb.^2)].^(0.5), is at T0. Note that for 2-polarization waveforms that include an inclination angle (eg, DS2P) different inclination angles will cause hp, hc to be weighted differently and therefore will produce different shifts.

The cusp waveform (generated by P. Shawhan’s cuspgw function) and most astrophysical waveforms that are loaded from files are always 1 sec long with sampling rate 16384 Hz when created/loaded. These are resampled linearly and truncated or zero-padded to the desired length. One should be cautious in using T<1 for these waveforms.
