 The algorithm transforms a single spectrum workspace containing 
 spectral density :math:`S(Q)`, :math:`S(Q)-1`, or :math:`Q[S(Q)-1]` 
 (as a function of **MomentumTransfer** or **dSpacing** :ref:`units <Unit Factory>`) to a PDF 
-(pair distribution function) as described below.
+(pair distribution function) as described below. The available output types are the reduced pair
+distribution function :math:`G(r)`, the pair distribution function :math:`g(r)`, and the radial distribution
+function :math:`RDF(r)`.
 
 The input Workspace spectrum should be in the Q-space (\ **MomentumTransfer**\ ) :ref:`units <Unit Factory>` .
 (d-spacing is not supported any more. Contact development team to fix that and enable **dSpacing** again)
