Typical migration of quadrants due to errors in the data when using the analytic formula. The continuous lines represent the penalty functions \(C_{{L_{2} }} \left( \theta \right)\) for a single period for two realizations. The circles correspond to the estimates using the analytic formula. The black circle falls on the first quadrant exactly at the minimum of the penalty function and the same happens for the red circle at the fourth quadrant. The dashed lines indicate that the periodicity of the penalty functions is 90°
