 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Automatic type deduction will also work with the following signature:
-``void (const R&, T1 t1, T2 t2 ..., TN tn)``
+``void (R&, T1 t1, T2 t2 ..., TN tn)``
 
 This will be more efficient when ``R`` is of type ``itk::VariableLengthVector<T>`` and should be preferred in this case.
