The probe-response correction depends on the dimensions of the shear probe. For a commonly used shear probe the spectrum is corrected for the spatial averaging of the shear probe by multiplying it by the factor <math>1+\left( \frac{k}{k_0} \right)^2</math> where <math>k_0</math> = 50 cpm and <math>k</math> is the wavenumber expressed in units of cpm [1] The correction reaches a factor of 10 at a wavenumber of 150 cpm, and it is not recommended to use spectral data beyond this wavenumber unless your shear probe is small enough to have a cutoff wavenumber <math>k_0</math> that is larger than 50 cpm.
