Abstract: A three dimensional method for the analysis of data cubes is presented. It is applied on Ne ii line data of the ionized feature in the inner 3 times 4 pc of the Galactic Center, called the Minispiral. The data cube can be viewed as a whole and different structures can be easily and clearly separated. A simple model of rotating material in different plains is fitted in three dimensions. Thus the location of the emitting material can be determined in the real three dimensional space and can be viewed as such. It is shown that the emission features of the ionized gas can be explained by a minimum number of 3 plains.
