Tables 5 and 6 present calculated column densities (in units of molecules per cm^2^) of various species in the ultracompact core (UCC), the compact core (CC) and the halo, together with the total column density and the observed column density where available. Table 5 gives column densities at a time of 3x10^3yrs in the UCC and CC components and at 10^5yrs in the halo. Table 6 gives column densities at a time of 10^4yrs in the UCC and CC components and 10^5yrs in the halo.
