Fig. 2(Color online) Ten times different error areas in the polar coordinate system between F1+2 = (26.3,15.2) and F4+5 = (15.2,26.3) due to 10 times different precision in the angle between θ1+2 and θ4+5. The error area for both exercises in the rectangular coordinate system is the same, which is clear in (a).
