mixsea.shearstrain.find_cutoff_wavenumber

mixsea.shearstrain.find_cutoff_wavenumber(P, m, integration_limit, lambda_min=5)[source]

Find cutoff wavenumber for spectrum integration.

Parameters:

P (array-like) – Spectrum
m (array-like) – Vertical wavenumber vector
integration_limit (float) – Variance limit for integration
lambda_min (float, optional) – Minimum vertical wavelength lambda_z=2pi/m, by default 5

Returns:

iim – Integration range as indexer to P.

Return type:

array-like
