Notes. (a) Laboratory wavelength; (b) flux summed over all pixels in 10-18 W m-2. Typical line flux uncertainties are dominated by calibration uncertainties ($\sim$30-50%) and fringing (0.1 Jy at the longest wavelengths to 0.6 Jy at the shortest); (1) lines blended with above line; (2) Line detected only in central spaxel and should not be compared to the fluxes of the summed spaxels; (3) doublet unresolved.
