\caption{From the table containing all the emission lines found in
the spectrum, available at the CDS. The first column is the
wavelength in angstrom; the second column the relative {peak}
intensity; the third column contains the molecule name (or "Unid''
when the line is unidentified); electronic, vibrational and
rotational transitions are given in the last columns. In the list
we have included many blended lines noted with a " + '' sign.
