Distribution of the SFRs of the 82 BRCGs of our sample. SFRs were estimated from infrared luminosities L_IR using the relation of Bell (2003). We estimated L_IR by fitting a modified blackbody with a fixed dust emissivity spectral index, β = 1.5, and a fixed dust temperature, T_dust = 35 K, to the Herschel photometric points. The only other free parameter was the redshift of the sources z (see Planck Collaboration XXVIII 2014 for details). For comparison with our estimated SFRs, we show the total SFR in the 80 kpc core of CL J1001+0220 at z = 2.506 (Wang et al. 2016) and the estimated SFR of the brightest Herschel source in the core of ClG J0218.3–0510, a protocluster located at z = 1.62 (Santos et al. 2014). It is interesting to note that the total SFR in the core of CL J1001+0220 is comprised of nine luminous star-forming galaxies that are resolved from a single bright Herschel SPIRE source (Wang et al. 2016).
