class lib.theory.fog.LorentzianFoG

Bases: object

Lorentzian Finger-of-God.

Methods

__call__(k, mu, sigmav=0.0, grid=True)

Return Lorentzian FoG damping.

Parameters

• k (array) – Wavenumbers.

• mu (array) – Angle to the line-of-sight.

• sigmav (float, default=0) – Velocity dispersion.

• grid (bool) – Whether input k, mu should be interpreted as a grid, in which case the output will be an array of shape (k.size, mu.size).

Returns

fog

Return type

array
