Fig. 2
[CII] spectra obtained at specific locations in NGC 6720 with GREAT. The #4 (rescaled by 0.5), #3, and #5 spectra have been shifted vertically by − 0.3, − 0.7, and − 1.0 K for clarity. The “cen+ring” spectrum is an average of broad spectra found at the central (position #1) and four symmetric locations on the major and minor axis (positions #3,#5,#8,#8a).
