+        Return the multipole normalization ``k_m`` and orientation angle ``angle_m``.
+
+        The multipole normalization and angle are computed from the multipole component
+        parameters ``(epsilon_1, epsilon_2)`` using
+        :func:`convert.multipole_k_m_and_phi_m_from`. The returned angle is converted
