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) Assumed according to the p-H2CO analysis of the outflow component (see text). (d) Column density refers to the sum of A and E species. (e) Column density is corrected for opacity as derived by fitting the hyperfine line pattern (see Table 3). (f) Assumed as hot corino (see Section 4.4.3). (g) Tempera- ture range assumed from the CH3OH and OCS rotational diagrams in L1551-IRS5. (h) Source averaged column densities can be derived by applying the filling factor reported in Table 6 for c-C3H2 as an envelope tracer.
