	Figure 1: Schema illustrating the main kinematical structures in the longitude-velocity diagram of the inner degrees of the Galaxy. The labels A to D stand for Sgr A to Sgr D complexes. See the text for an explanation of the other labels.

Figure 4: In grey-levels and contours we show the longitude-velocity diagram obtained with the CO(1-0) data by Bally et al. (1987) at different latitude ranges. We also indicate the different kinematical features discussed in this paper (note that not all the features that are seen in different panels are labeled in all of them). Blue triangles and bars represent the peak velocity and the full width at half maximum (FWHM) of the sources detected in CS. Black points and bars show the peak velocity and FWHM of the sources that have been detected in CS and SiO.

Figure 5: In grey-levels we show the longitude-velocity diagram obtained integrating the CO(1-0) data by Bally et al. (1987) in the latitude range . Red triangles and bars represent the peak velocity and the full width at half maximum (FWHM) of the radio recombination lines detected in the longitude range (Pauls & Mezger 1975). Blue squares and bars represent the peak velocity and the FWHM of the radio recombination lines detected at and (Paladini et al. 2003).

	Figure 3: CS(2-1) spectra (black lines) and SiO(2-1) spectra (multiplied by 2, green lines) towards all the observed positions, which are written in the upper-left corner (in Galactic coordinates). The positions observed with the 30m telescope are indicated with a label (a). The velocity scale is the same for all the spectra in the same column.
