Stellar mass vs. star formation rate (derived from the Hα line) for the complete sample of HAEs (grey dots) discovered in the field of MRC1138−262 (Koyama et al. 2013a). Only DKB07 and DKB08a are excluded as the estimates of the stellar mass of the associated HAEs are unreliable. The pink dots indicate the HAEs located within the LABOCA beam aperture for all LABOCA source. The SFR based on the FIR measurements is shown as open pink stars (connected with dotted lines). The FIR measurements reveal that FIR bright HAEs (LABOCA sources) are off the star-formation main sequence for z ~ 2 galaxies (Daddi et al. 2007; Santini et al. 2009).
