Summary
Velocity spectra estimated from a 128-s long segment of observations. The original spectra (black) were estimated using 7 fft blocks, each 32 s long with a 50% overlap and Hanning window applied in the time-domain on each block. The colored lines are the same spectra but obtained using an alternate spectral averaging strategy. The purple has 58 degrees of freedom.
