Observed-frame 1D spectra (black curve) of the sources showing either Lyα in emission or in absorption in rest-frame UV spectra. In red we show the best fit model spectra. From the top BX1, BX10, LAE27, z3LAE2, BX16, LBG11. The first, second and third panel columns represent Lyα (from MUSYC and GOODS-VIMOS surveys), [OIII]doublet and Hα wavelength ranges respectively. Dashed vertical lines indicate the wavelength of sky emission lines, which could leave residuals in the science spectra. Horizontal dashed blue lines indicate the continuum rms in the wavelength range where we did not see an expected emission line. As LAE27, z3LAE2, and LBG11 are at z ~ 3, Hα line would fall outside the MMIRS coverage. The rest-frame optical emission lines are unresolved.
