Notes. The ± 1σ standard deviations are given in brackets. TOTAL: calculated from total column densities N given in Table 4. Q(2), Q(4): calculated via Eq. (6) from NJ1 values in Table 3. AV (a): mean of Q(2) and Q(4) and mean absolute deviations (MAD). EXPEC: statistically expected values for 12C/13C = 20.
