Wavenumber response of the shear probe

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 $1+{\left(\frac{k}{k_0}\right)}^2$ where $k_0$ = 50 cpm and $k$ is the wavenumber expressed in units of cpm 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 $k_0$ that is larger than 50 cpm.
