Stacked cutouts of NUVrJ–based SFGs at 0.8 < z < 1.2, as a function of M_⋆ (left to right, expressed in log M_⊙). Within each bin, we stacked only those sources with S/N < 3 at a given band. SCUBA 850 μm and AzTEC 1100 μm images are smoothed with a Gaussian kernel to ease the visualisation. Each cutout size is 8 × FWHM of the PSF, while for Spitzer-MIPS, we chose 13 × FWHM. Below each cutout, we report the corresponding S/N.
