Same as Fig. 1, but for artificially created ARs. The black diamonds represent the results of the symmetric bipolar ARs. The purple triangles represent the results of the weakly asymmetric bipolar ARs. The blue squares represent the results of the strongly asymmetric bipolar ARs. The red asterisks represent the results of the complex ARs. Panel a: results of the generalized method that we introduce; panel b: results of the BMR-based method. We note that for panel b, three points of the complex ARs lie beyond the displayed range, with the most extreme point (−0.092, −0.22).
