Notes. The numbers in parentheses represent the errors in units of the last significant digits. N(HC3 N J = 10–9) and N(HC3 N J = 2–1) represent the HC3 N column density derived by the J = 10–9 transition and J = 2–1 transition, respectively. The column densities of CCH are derived by RADEX code. The column densities of N2 H+ are derived by Tex obtained by HFS fitting.
