%      1999-12-01 (DaB) Created
%      2000-02-17 (GS)  The second input argument ('X') in 'size(xDSLlist,X)'
%                       was changed to the value of 2 because each of
%                       the systems to be investigated should be
%                       represented by their specific PSD's and not
%                       only by their generic name definitions.
