directions	`character` vector with two spatial directions: acombination of x, y, and z. e.g xx, xy or yz.
k_perp	`numeric` length of component of wavevector perpendicular to the magnetic field.
k_par	`numeric` length of component of wavevector parallel to the magnetic field.
omega	`numeric` angular cyclotron frequency of current fluctuations.
omega_c	`numeric` particle angular cyclotron frequency (omega_c = qB/m).
mass	`numeric` particle mass in kg.
distribution	`list` with the velocity distribution.
