Table 1: Total column-densities (in cm^-2) of species of interest with their relative yields. c and C are the column-densities across the small and big cloud calculations without turbulent diffusion. c_t is for the small cloud when maximum turbulent diffusion is included with $L=8 \times 10^{-2}$ pc. $C_{\rm t2}$ and $C_{\rm t10}$ are the results for the big cloud and turbulent diffusion with a correlation length L₂=2L and L₁₀=10L respectively. The relative yields are computed as $y=c_{\rm t}/c$ , $y_2=C_{\rm t2}/C$ and $y_{10}=C_{\rm t10}/C$ . Note that the yields are not strictly 1 for (H+2H₂), O and C⁺: this gives an estimate of the mass conservation error in the code for individual species. Column-densities as observed in the $\zeta$ Per line of sight are provided in the last column. The last row diplays the ratio of H₂O to OH column-densities. The last column contains the observed column-densities as quoted by Le Petit et al. (2004).
