Notes. Redshift uncertainties are dominated by the wavelength calibration uncertainty (equivalent to ±0.0008). The S/N values are derived from the integrated flux of the line and its uncertainty. From spectral fits, we have then obtained Hα line fluxes and luminosities, corrected from slit-loss but without any correction for extinction. For C1a, due to a broad emission line, we have large uncertainties in the fit of the Hα emission.
