Distribution of the PCl J1001+0220 spec-z members (red diamonds and histogram) and coeval field galaxies (navy points and histogram) in the SFR- plane as estimated by LE PHARE. Histograms are normalized as in other figures such that the area is identical for both samples. The upper limit to the radio-derived SFR of spec-z member and coeval field galaxies coming from stacked 3 GHz JVLA data is shown as the green and light blue lines/arrows, respectively. The lack of detection for both proto-cluster members and coeval field galaxies suggests that prodigious dusty star formation (IRX ≲ 10) is no more common in the proto-cluster than in the overall field at these redshifts and is not particularly common in either environment.
