Notes. The LTE excitation temperature Tex,43 is derived from the optically thick I43 emission, Tex,74 is derived from R74 The C column densities are derived assuming LTE and optically thin [C i] emission. Values of the integrated intensities of C
O 2–1 are given as presented in Nürnberger et al. (2002) along the two cuts, the LTE excitation temperature is derived from I43. The LTE column densities of CO, and the total gas column density assume an isotope ratio of 500 and CO:H2 = 8 × 10-5 (Frerking et al. 1982), i.e. a ratio of C18O/H2 = 2 × 10-7.
