 ### Determining Corrections
 
+Move to the `Corrections` tab.
+
+- Keep the method set to `Global` correction scheme.
+- For `Observables to correct` select `DQ2` or `DQ3` to correct $Q''$ or $Q'''$. Adapt the selection to the fitted order from the previous step.
+- Click `Correct` to compute corrections for the given settings.
