Scaling relation between the prediction index output by the U-net p and the flux in the MILCA y map. In blue we plot the fluxes of the 20 204 sources that are detected on the full sky with the U-net, stacked on the SZ MILCA y map as a function of their associated prediction index p. For comparison, the average flux in the MILCA y map of the PSZ2 clusters is shown in orange, the average flux of the MCXC clusters is shown in green, and the average fluxes of the RM₅₀ and the RM₃₀ clusters are shown in red and purple, respectively. Error bars are computed with the bootstrap method.
