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 to any hysteresis with (point-)symmetric behavior. The implementation of the method is demonstrated exemplarily using intermixed longitudinal and transversal data obtained from a chromium-doped ternary topological insulator revealing a clear hysteresis. Furthermore, by introducing a mathematical description of the anomalous Hall hysteresis based on the error function precise values of the height and coercive field are determined.
