SFR vs. stellar mass of our full galaxy sample. Sources at 5.5 < z < 7.5 with new and archival C III] data, galaxies at z ∼ 2 with archival C III] data, and literature sample at 6.0 < z < 7.5 are shown as blue, green, and orange circles, respectively. The best-fit relations for the main sequence (MS) at 5.5 < z < 7.5 and 1.7 < z < 2.0 from Schreiber et al. (2015) are shown as magenta and red bands, respectively.
