Color-magnitude diagram color-coded by photometric redshift. Our criteria (in red) for selecting OFGs are: H > 26.5 mag & [4.5] < 25 mag. We note that we include sources outside the wedge whose 1σ photometric uncertainties overlap the wedge, so we have points outside the red triangle. The arrows show our H-dropouts (S/N < 3), with the typical depth of H = 27 mag (5σ) in the shallowest region of the HLF survey as their lower limits. The blue shaded area describes the distribution of all the IRAC detected sources (see Appendix A for more details) in the GOODS-ALMA field. The blue and red triangular regions are the same as in Fig. 2.
