One LBG is detected ($5.2\\sigma$ at peak emission), while the others remain individually undetected at the $3\\sigma$ level. The average FIR luminosity of the sample is found to be $L_{\\rm FIR} \\simeq 2 \\times 10^{11}\\,{\\rm L}_{\\odot}$, corresponding to an obscured star-formation rate (SFR) that is comparable to that inferred from the unobscured UV emission.
