 \caption{Properties of the four datacubes used in our analysis. For the
analysis of the detailed morphology of \eso{} we use the long-baseline
datacubes~NL and~UL, which have a~high spatial resolution. For the
derivation of the global structure of \eso{} we use the datacubes~NH and~UH,
which contain only the short baseline observations. The latter datasets are
therefore deeper than the former, but have lower spatial resolutions. }
