ABSTRACT:
We used [\ionNeii] line emission data (12.8 micron ), in order to investigate
the detailed kinematic structure of the inner 3 * 4 pc of the
Galaxy. The quality of [\ionNeii] as a tracer of ionized gas is
examined by comparing it to radio data. A three dimensional representation
of the data cube allowed an exact distinction of the different features,
which are reviewed in detail. A model of rotating gas in different plains
is fitted to the data. Thus a classification of the different
features could be made. It was found that most of them are
situated together with the CND in the main plain. Finally we reconstructed
the real three dimensional space with the help of the model.
