Module LALInspiralWaveCorrelate.c

Module to compute the correlation of two data sets. Suitable only when REAL4VectorFFT is used (i.e. rfftwi_one of fftw).

Notation: The input struct has two vectors: signal1 and signal2. This module computes the correlation by shifting signal2 with respect to positive time-direction relative to signal1. Thus, if signal1 denotes the detector output in which a signal, say signal2, is present at time $t_0,$ then the correlation peaks at $t_0.$
