bilby.core.utils.series.nfft

bilby.core.utils.series.nfft(time_domain_strain, sampling_frequency)

Perform an FFT while keeping track of the frequency bins. Assumes input

time series is real (positive frequencies only).

Parameters:

time_domain_strain: array_like

Time series of strain data.

sampling_frequency: float

Sampling frequency of the data.

Returns:

frequency_domain_strain, frequency_array: (array_like, array_like)

Single-sided FFT of time domain strain normalised to units of strain / Hz, and the associated frequency_array.
