pspec_likelihood.likelihood.DataModelInterface.apply_window_function

DataModelInterface.apply_window_function(discretized_model: Annotated[Quantity, Unit('mK2')]) → Annotated[Quantity, Unit('mK2')]

Calculate theoretical power spectrum with data window function applied.

Simply performs the matrix product \(p_w = W p_m\).

Parameters:

discretized_theory – The discretized theoretical power spectrum, discretized in such a way as to be compatible with the window function. This can be calculated with discretize_theory().

Returns:

A 1D array of power-spectrum values corresponding to kpar_bins_obs`.

Return type:

windowed_theory
