modes

modes(self, ell_max=None, **kwargs)

Source: spherical/grid/utilities.py

Return mode weights of function decomposed into SWSHs The output array has one less dimension than this object; rather than the last two axes giving the values on the two-dimensional grid, the last axis gives the mode weights.

Parameters

• ell_max: {None, int}, optional

  Maximum ell value in the output. If None, the result will have enough ell values to express the data on the grid without aliasing: (max(n_phi, n_theta) - 1) // 2.

• **kwargs: Any

  Additional keyword arguments are passed through to the Modes constructor on output
