 The calibration settings are organized in three blocks:
 
 1. Input directories
-2. Pixel calibration
+2. Pixel (full) calibration
 3. Advanced settings
 
 The input directories will be used when looking for run files
 (Vanadium and Ceria). They effectively become part of the search path
 of Mantid when using this interface.

+The pixel (full) calibration file contains the calibration details of
+every pixel of all banks, as produced by the algorithm
+:ref:`EnggCalibrateFull <algm-EnggCalibrateFull>`. A default pixel
+calibration file is provided with Mantid packages. This calibration
+has been produced for the Vanadium and calibration sample (Ceria) runs
