Dust emission of the detected Hi-z LBGs with S/N_submm >  3 (11 data points) are normalised at λ_{rest − frame} = 200 μm and combined to form a single Hi-z LBG template. For each detected LBG in our sample, we use the number of S/N_submm >  3 ALMA detections, which are validated in agreement with our criteria, as described in Table 1. The redshift range (5 ≲ z ≲ 10) makes it possible to cover a wide wavelength range and explore dust emission. We over-plot colour-coded curves for SEDs based on modified blackbodies in the range 30 ≤ T_dust [K] ≤ 85.
