Comparison of the radial variation in the SMG fraction. The green bar indicates the expected SMG fraction for a homogeneous distribution. The small symbols are the values for each individual field. The large symbols are the stacked results for corresponding types of fields. Poisson noise is assumed as the associated uncertainty. We can see that SMGs are concentrated in the central 1.5′ in general, while more SMGs can be from at 3′≤r < 4.5′ in the 4C 23.56 field.
