Notes. X(−Y) means X × 10−Y. All the ionic concentrations were found, assuming Ne = 10 000 cm-3. C+, C2+, and N2+: the IUE fluxes are used. ** The ionic abundance for Ar3+is from the derivation by λλ4711,40. When Ne = 80 000 cm-3 is used, the ionic abundance value derived by λλ7171,7263/37, i.e., 8.40(-7), is also close to the one derived by λλ4711,40: see the text.
