s is one, so that psd=yk**2.</p>
<p>The fft’s are computed using SCIPY FFT codes, and parallel FFT can 
potentially speed up the calculation. Up to KSPEC works are sent.
The yk’s are saved to get phase information. Note that tapers are 
applied to the original data (npts long) and the FFT is zero padded
up to NFFT points.</p>
