factors_to_fir_kernel

(

coh_facs

)

Compute a finite impulse-response filter kernel from a power
spectral density conforming to the LAL normalization convention,
such that if zero-mean unit-variance Gaussian random noise is fed
into an FIR filter using the kernel the filter's output will
possess the given PSD.  The PSD must be provided as a
REAL8FrequencySeries object (see lal's swig binding documentation).

The return value is the tuple (kernel, latency, sample rate).  The
kernel is a numpy array containing the filter kernel, the latency
is the filter latency in samples and the sample rate is in Hz.
