+The magneto-optical part is optional. To enable this part do the following.
-It allows you to define a magnetization in the system and fit it.
+  * In the magneto-optics sheet click on "add magnetization".
+  * give the magnetization direction of all layers and click on apply to all layers. This can be changed on a per layer base in the Properties dialog for each layer.
+  * In case of measurements with circular light the polarization should be set to left and right circular polarization.
+  * In the preferences menu activate the following
+    * To enable full accuracy of calculation enable the Zak matrix formalism as algorithm.
+    * Check which asymmetry definition for the data you want to use.
+    * Treat dm and bm as magnetic contribution.
+  * Load the asymmetry files of your measured data.
+  * Fill the columns deltam and betam with proper values. The definition is given in the Terms and Definition document.
+  * Use the mode asymmetry.
+Note that the Parrat algorithm is able to calculate magnetic contributions as an approximation. But the polarization must be set to circular light to work properly.
