Abstract: We present a symmetrization routine that optimizes and eases the analysis of imperfect,experimental data featuring the anomalous Hall hysteresis. This technique can be transferred toany hysteresis with (point-)symmetric behavior. The implementation of the method isdemonstrated exemplarily using intermixed longitudinal and transversal data obtained from achromium-doped ternary topological insulator revealing a clear hysteresis. Furthermore, byintroducing a mathematical description of the anomalous Hall hysteresis based on the errorfunction precise values of the height and coercive field are determined.
