The bias induced by the Goodman algorithm
From Atomix
The bias induced by the Goodman [1] vibration-coherent noise removal algorithm is corrected by dividing the spectrum by [math]\displaystyle{ 1-\frac{1.02N_v}{N_f} }[/math] where [math]\displaystyle{ N_v }[/math] is the number of signals that are used to remove coherent noise in the shear-probe spectrum and [math]\displaystyle{ N_f }[/math] is the number of fft-segments that are used to estimate the shear spectrum [2].
