Lyman α luminosity versus absolute UV magnitude, with redshift encoded in the color bar. On the top (right) are UV absolute magnitude (Lyα luminosity) histograms for the three samples, stacked on each other, using the same colors as in Fig. 4. Galaxies in Samples 2 and 3 have upper-limit estimations of their Lyα and UV fluxes (see text for details). All values have been corrected for magnification but not for possible dust extinction. The thick blue line displays the locus of the SFR_Lyα = SFR_uv for a constant star-formation system. The dashed violet, pink, and orange lines correspond to the best fit for the offset in this relation (with fixed slope) when the sample is split in the redshift bins: 2.9 <  z <  4.0, 4.0 <  z <  5.0, and 5.0 <  z <  6.7, respectively. Uncertainties on offset values are shown as vertical lines of the same color. The three vertical gray dashed lines correspond to M₁₅₀₀ = −17, M₁₅₀₀ = −15, M₁₅₀₀ = −13, which correspond roughly to the observational limit reached in blank fields, lensing fields, and the extrapolation needed to ensure that the UV LF provides enough ionizing flux for reionization (see Bouwens et al. 2015a). Red and blue arrows indicate the effect of a magnification factor of μ = 5 and a reddening A_V = 0.5 magnitudes, respectively.
