Left: EPVG (magenta, top) and HPVG (red, bottom) molecular cloudlets, numbered, for which we have extracted their ¹²CO J = 3–2 spectra. The gray images show the ¹²CO J = 3–2 line emission integrated in the velocity interval displayed in each panel. The green contours shows the ionized gas emission in the same velocity range ([Ne II]12.8 μm line from Irons et al. 2012). Sgr A^* is displayed with a black dot. Right: EPVG (magenta) and HPVG (red) cloudlet spectra. The numbers correspond to their position in the left panels. In each panel the velocity axis has a common width of 125 km s⁻¹. Gaussian line fit parameters are tabulated in Table B.1.
