-If no *ReferenceWorkspace* is given, the algorithm takes the L1 distance :math:`l_1` from the instrument attached to *InputWorkspace* and calculates the average L2 distance :math:`l_2` using the histograms specified by *ReferenceSpectra*. The algorithm also needs to know the TOF :math:`t_{elastic}` corresponding to the zero-energy transfer. This is either taken from the first spectrum in *InputWorkspace* as the bin centre of the bin specified by *ElasticBinIndex*, or calculated from the elastic peak positions given in *EPPTable*. *EPPTable* should be in the format returned by the :ref:`algm-FindEPP` algorithm. In this case the algorithm averages the `PeakCentre` column for histograms listed in *ReferenceSpectra*. Finally, the algorithm needs the incident energy :math:`E_i` which can be either specified by *IncidentEnergy* or is taken from the sample logs of *InputWorkspace*. In case *IncidentEnergy* is specified, the 'Ei' and 'wavelength' sample logs of *OutputWorkspace* are updated accordingly.
