The emission lines in this table are a subset of lines from the catalog by Meinel et al. (1975) which were used in plasma diagnostics of planetary nebula by Acker et al. (1989).

Observed Wavelength Wavelength observed in the planetary nebula spectrum in Å, by Acker et al. (1989).
Element Emission line is identified with a particular ion (forbidden lines in square brackets e.g.  [ O III ])
Laboratory Wavelength Highly accurate wavelength observed in laboratory spectrum in Å, by Meinel et al. (1975)
Mult. Multiplet number from Revised Multiplet Tables by Moore (1945)
Lower Level Final state of quantum transition
Upper Level Initial state of quantum transition
Upper Level
Excitation (eV)		 The excitation potential of the upper level of the transition above the ground level of the ion (in eV)
