angle_factor#
- empymod.kernel.angle_factor(angle, ab, msrc, mrec)[source]#
Return the angle-dependent factor.
The whole calculation in the wavenumber domain is only a function of the distance between the source and the receiver, it is independent of the angel. The angle-dependency is this factor, which can be applied to the corresponding parts in the wavenumber or in the frequency domain.
The
angle_factorcorresponds to the sine and cosine-functions in Eqs 105-107, 111-116, 119-121, 123-128.This function is called from one of the Hankel functions in
empymod.transform. Consult the modelling routines inempymod.modelfor a description of the input and output parameters.
