Stacked 1D spectrum of six z ∼ 2 galaxies from the MUSE sample. The stacked spectrum is the weighted average of the rest-frame UV spectra of the six galaxies. The spectral resolution is set to Δλ = 0.05 nm. Rest-frame positions of the [CIII]λ1907 and CIII]λ1909 line are shown as yellow and red lines, respectively. Wavelengths with skyline contamination are shown as vertical gray regions.
