{\label{tablediag} Results from diagnostic diagrams\protect\footnote{The second column gives 
the distance from the centre to the first spectra
(marked with the letters "a'' and "A'' in the diagnostic diagrams). 
In the third column, 
the orientation of the small and capital letters is listed.
The maximum [\ion{O}{iii}] radius ({\it S/N} $>$ 3) at the
same PA~taken from literature is given in the fourth column.
We also give the
 [\ion{O}{iii}] radius ({\it S/N} $>$ 3) observed from our
spectra (Col.~5). In the sixth column, the radius is given until which we
were able to plot line ratios in the diagnostic diagrams.  In the last column, 
the radius of
the NLR as determined from the diagnostic diagrams is given in \arcsec~and, in
brackets, pc, respectively.
The two objects with a clear transition between
NLR and \ion{H}{ii} region are marked in bold.}}
