Fig. 8
Non-LTE C2H line intensity predictions with RADEX vs. the observed line intensities (black symbols). Top panel: the models correspond to parameters of n(H2) = 106 cm-3, Tkin = 100 K, N(C2H) = 8 × 1013 cm-2 (green symbols), and to n(H2) = 5 × 106 cm-3, Tkin = 400 K, N(C2H) = 2 × 1013 cm-2 (blue symbols). The sum of the two components is given by the red symbols. Bottom panel: the models correspond to parameters of n(H2) = 105 cm-3, Tkin = 150 K, N(C2H) = 8 × 1013 cm-2 (green symbols), and to n(H2) = 5 × 106 cm-3, Tkin = 400 K, N(C2H) = 2 × 1013 cm-2 (blue symbols). The sum of the two components is given by the red symbols.
