Notes. The laboratory wavelengths of the emission lines are taken from the NIST database (http://physics.nist.gov/asd3, Ralchenko et al. 2011). The error in the EW is assumed to be 5% of the determined value. The errors in the peak values (λ, v) are based on the errors in the Gaussian fit parameters. The errors in λ and v are underestimated in the case of deviations from a Gaussian shape ([S II], [Fe II]). See the text for more details.
