mt.f_fromSW

f_fromSW(j, B, gamma=2.5, p=1)[source]

Get the theoretical maxima distribution for a Sachs-Wolfe-like spectra filtered with a Mexican needlet.

For more information, see 1.

Parameters

  • j (float) – Frequency j of the Mexican needlet

  • B (float) – Parameter B of the Mexican needlet.

  • gamma (float, optional) – Parameter gamma for the Sach-Wolfe spectra. In the CMB, 2 < gamma < 3.

  • p (int, optional) – Order of the Mexican needlet

Returns

Theoretical distribution of the maxima, f.
