The bias induced by the Goodman algorithm

The bias induced by the Goodman vibration-coherent corrections algorithm is corrected by dividing the spectrum by $1-\frac{1.02N_v}{N_f}$ where $N_v$ is the number of signals that are used to remove coherent signals in the shear-probe signals and $N_f$ is the number of fft-segments that are used to estimate the shear-spectra.
