Images of the SPHerIC candidates at 4.5 μm which are 4σ overdense within a radius of 1′. Each image is ∼ 2.4′×2.4′. IRAC sources with [3.6]−[4.5] > (<) −0.1 are indicated by red (blue) circles. Contours of significance of the overdensities are shown green-yellow-salmon-orange-red lines starting at 2.5σ and incremented in 0.5σ steps. Herschel emission 3σ isocontours at 350 and 250 μm are shown as black and gray lines respectively. The large white circle has a radius of 1′ and is centered on the peak of emission at 350 μm from SPIRE.
