Total linear polarization (in terms of Q₀)and plot of Q vs. U (defined with respect to a fixed direction in the sky corresponding to U = 0 when perpendicular to the rotation axis) with varying rotational phase. The magnetic dipole strength has been fixed at 70% of the critical Hanle field, and the fixed astrographic latitude of the magnetic pole is 30, 45, and 60 degrees for the dashed (crosses), continuous (stars), and dotted (diamond) lines respectively.
