mt.f_fromcl

f_fromcl(cls)

Get the theoretical maxima distribution f, from the angular power spectra C_l of a map.

For more information, see 1 or 2 (in the latter, k_1 corresponds to (kappa_j)^2 and k_2 to (eta_j)^2).

Parameters

cls (np.ndarray) – Angular power spectrum of the map.

Returns

Theoretical distribution of the maxima, f.

Return type
