Synthetic ALMA flux density maps (gray coded) for a wavelength of λ = 850 μm (left column), λ = 1.3 mm (middle column), and λ = 3.0 mm (right column) at a distance of 140 pc overlaid with vectors of linear polarization considering RAT alignment for inclination angles of i = 0° (top row), i = 30° (middle row), and i = 60° (bottom row). The length of the vectors depends on the degree of linear polarization. For better comparison the color bar is fixed between F_min = − 4.0 log ₁₀(Jy / beam) and F_max = − 2.0 log ₁₀(Jy / beam) in all plots. The blue areas indicate where the helical magnetic field morphology is potentially detectable according to the LOS analysis.
