Hanle diagrams show the Q/I and U/I amplitudes in the presence of magnetic field at the line cores of the triplet calculated with μ = 0.1. The top, middle, and bottom panels correspond to θ_B = 90°, θ_B = 60°, and θ_B = 30°, respectively. The thick lines correspond to constant strength magnetic field of 0.008, 0.02, 4, and 8 Gauss with the azimuth 0°<χ_B< 180° (thick solid line) and 180°<χ_B< 360° (thick dotted line). The thin lines correspond to the azimuths χ_B = 0° and χ_B = 180° thin (dot-dashed line), χ_B = 30° and χ_B = 150° (thin dashed line), χ_B = 60° and χ_B = 120° (thin dotted line) and χ_B = 90° (thin solid line). The anisotropy factors, collision rates and continuum are the same as those producing Fig. 4.
