Logarithmic ratio between SFRs computed with Eq. (8) using Lyα luminosity and EW₀ and the “true” SFR, measured directly from dust-corrected Hα luminosity (given our definitions, log₁₀(SFR_{Lyα(This  work)}/SFR_Hα) = log₁₀(f_{esc, Lyα(Hα)}/f_{esc, Lyα(This  work)})). The standard deviation (σ) and σ/ (N: number of sources) are computed in ±30 Å bins and indicated in light and darker grey. We find a relatively small scatter which may decrease for higher EWs and that is at the global level of ±0.12 dex for the typical definition of LAE at higher redshift (EW₀ >  20 Å), but rises to ≈0.2 dex at the lowest EWs. We also provide a comparison of the typical scatter between UV and FIR SFRs in relation to Hα at z ∼ 0−2 (≈0.3 dex; see e.g. Domínguez Sánchez 2012; Oteo et al. 2015).
