Notes. (a) Temperatures and column densities as derived from rotational diagrams (see Table 5). (b) Temperature range assumed from the D2CO and c-C3H2 analysis of the envelope emission (see text). (c) Assumed according to the p-H2CO analysis of the outflow component (see text). (d) Temperature range assumed from the CH3OH and OCS rotational diagrams (e) Column density refers to the sum of A and E species. (f) Column density is corrected for the opacity as derived by fitting the hyperfine line pattern (see Table 3). (g) Column density is corrected for opacity (see Sect. 4.2). (h) Source averaged column densities can be derived by applying the filling factor reported in Table 6 for c-C3H2 as an envelope tracer and for CH3OH and CH3CN as hot corino tracers.
