Profiles of the magnetic field magnitude B, magnetic field components B_y and B_z, and the δ angle along the x axis for a toroidal flux rope with the Tsuji (solid lines), Miller & Turner (dashed lines), and modified Miller & Turner (dotted lines) solutions (α> 0). The B_x component is zero for all solutions, therefore, it is not shown. Magnetic field is scaled by maximum value inside the respective flux rope. The δ angle, the angle between B and rot B, indicates how the force-free condition is fulfilled; this angle is zero for the Tsuji solution. Two columns are plotted for two aspect ratios, 2 (left) and 1.2 (right).
