Five examples of the spectra and line identification from the MOS sample. In the left panel of each subfigure, we show a snapshot of the deep Hα image centred on the galaxy, as well as the individual MOS aperture for each source. The right panel shows the spectrum of the galaxy obtained after reduction, with the IDs and redshift source in the upper-left legend. Using the Hα emission line, we indicate the estimated position of [O II], Hβ and [O III]λ5007 emission lines as well as four telluric absorption bands (in cyan), where some residuals of the sky subtraction are visible. The photometric fluxes from Moran et al. (2005) are depicted with blue, green and red circles for bands B, V and R, respectively. We also show the S/N of each fitted emission line below its name.
