Radial profiles obtained from the background- and foreground-cleaned stacked maps, for the sample of 645 clusters. The units here are MJy sr^-1. The black points correspond to the values obtained as the average of the pixels contained within each region considered and associated uncertainties have been obtained using bootstrap resampling. We find no significant detection at 100 and 143 GHz, while the detection starts to become strong at ν ≥ 353 GHz, consistent with what we saw in Fig. 2.
