 In order to use the tab, a new or existing calibration must be created or loaded (see above).
 
 The interface allows for two kinds of focusing:
 
 - **Normal Focusing:**
-    A run number can be entered and both banks will be focused.
-    The output workspaces will have a suffix denoting which bank they are for.
+    Run numbers can be entered and both banks will be focused for each workspace.
+    The output workspaces will have a prefix for the run they are for and a suffix denoting which bank they are for.
 
 - **Cropped Focusing:**
     The entered workspace can be cropped to one of the two banks or to a user defined set of spectra.
