Notes. From our VLA observations we quote the observed (gravitationally lensed) flux-densities and the rest-frame (unlensed) luminosities at 1.4 GHz. We give the estimated SFRs, corrected for the lensing magnification. For comparison, we also show the data from NVSS and the expected radio emission based on the optical/NIR derived SFR.
