M_dust vs. L_UV for the ALPINE targets. Blue and red points show individual FIR continuum detections at 4 < z < 5 and 5 < z < 6, respectively. Open downward triangles show 3σ upper limits of individual IR non-detections. Stacks with detections at z < 5 and z > 5 are shown as blue and red squares, respectively. The non-detection of stacks are indicated by a downward arrows. M_dust from the stacked ALMA continuum fluxes were estimated using the same expression as for the targets (Eq. (1)). The Bayesian linear fit of all the stacked values (detections and upper limits) is shown by the black and light blue lines, which also illustrate the probability distribution of the fit at 1σ confidence level. The resulting best fit is (dispersion dex, Pearson rank coefficient of 0.76 and p-value 0.08, with the Pearson coefficient computed considering all data as detections).
