Spectra of the [CII]158 μm emission observed with GREAT towards NGC 6720 obtained at different offsets from the center (see Table 1), overlaid on a H2 2.1 μm image (taken by David Thompson). The positions of the
GREAT beam, shown in cyan at the center (J2000 RA = 18:53:35.08, Dec = 33:01:45.0) are marked by crosses. The small tick marks are separated by 10 km s-1 on the velocity axis (Vlsr), and by 0.1 K on the intensity axis (
). The spectrum at position #4 has been scaled by a factor 0.75. The equator of the multipolar model we propose for NGC 6720 is shown by the green dashed circle with diameter 40′′.
