Notes. r0, φ0, and y0 are the initial values of the distance along the perpendicular jet axis, the azimuth angle, and the height along the jet axis, respectively; λ0 is the spatial wavelength of the initial perturbations; vy is the velocity component along the jet axis; Ψ is the half-opening angle of the helix; θ and α are the viewing angle and the position angle of the jet axis (defined as counter-clockwise from north), respectively.
