Given the already documented bias in the determination of intersecting remagnetization great circlesas a function of the parallelism of the circles, resulting in an elongated bias in that direction, wefound that rotational symmetry assumptions around the intersection would seem to be insufficient.In this contribution, we address the intersection and its inherent bias by doing bootstrap. Repeatedcalculations explore possible outcomes numerically; elongated distributions of the bootstrappedintersections are regarded as biased. The method calculates a more realistic confidence regionbased on the empirical distribution of the bootstrapped intersections.
