Notes. The two spectra were obtained with different slit widths and orientations, and have not been calibrated with independent photometricmeasurements, hence the line ratios relative to [O III] 5007 Å reported here. A dashed entry indicates that a given emission line was not clearly detected in the optical spectral fitting.
