Comparison of the fraction of the total flux residing in GDCs as a function of galactocentric distance. The blue filled circles and solid line show the total background-subtracted flux at 250 μm binned in radial distances of 0.5 kpc. The red open circles and dashed line show the flux at 250 μm due to GDCs in the same radial bins. The blue dotted line indicates 16% of the total flux, which is the average fraction of the total flux residing in GDCs.
