Notes. (a) Temperatures and column densities as derived from rotational diagrams (see Table 5). (b) Temperature range assumed from the c-C3H2 analysis of the envelope emission (see text). (c) Column density is cor- rected for the opacity as derived by fitting the hyperfine line pattern (see Table 3). (d) Column density refers to the sum of A and E species. (e) Assumed according to the p-H2CO analysis of the outflow component (see text). (f) Source averaged column densities can be derived by ap- plying the filling factor reported in Table 6 for c-C3H2 as an envelope tracer.
