Notes. Columns (1) and (2): fluxes for the [OIII] main and second emission line, respectively. Errors are calculated following Eq. (1). Columns (3) and (4): emission line FWHMs from Gaussian fitting of the spectral lines. Errors represent 1σ uncertainties from sampling statistics. Column (5): flux ratio between the [OIII] doublet emission lines. Errors are propagated from the flux errors.
