Main sequence of star-forming galaxies at z ∼ 4.5 and z ∼ 5.5. The filled squares are the measurements of average SFR from stacks; the open symbols are results from the literature; the magenta and orange lines are the fits of the main sequence at z ∼ 4.5 and z ∼ 5.5 respectively; the cyan and green lines are the fits of the main sequence from the literature. The colored stars are the individual galaxies in ALPINE with FIR continuum detections at > 3σ.
