Stellar mass and SFR diagram of our galaxies estimated using the SED fitting code LePhare (Ilbert et al. 2006; Arnouts et al. 1999). Top and right panels: detection rates (f_d) of continuum emission as functions of SFR and stellar mass. Filled and open points in the middle panel represent the continuum detected (> 3.5σ) and the non-detected galaxies (blue: z ∼ 4.5, red: z ∼ 5.5 galaxies), respectively. Solid and dashed lines show two different estimates of the z ∼ 5 main-sequence of star forming galaxies (Lee et al. 2012; Schreiber et al. 2015). Typical uncertainty of SFR and stellar mass are shown in the bottom right inset. The continuum detected galaxies mostly show stellar mass above ∼10¹⁰ M_⊙, and SFR above ∼30 M_⊙ yr⁻¹.
