Description:
The lines of 12CO, 12C12C, and 12CN used in the analysis are
listed in the table. The stars analyzed here are TX Psc, V Aql, and BL
Ori, and the lines selected for the analysis are listed for each star.
The data given in the table are the wavenumber, gf-value, and the
lower excitation potential of each selected line, together with the
observed equivalent width.
