Density of extragalactic radio sources with precise coordinates
This figure shows the density of radiosources with coordinates known with
precision better than 25 nrad (5 mas). The density is defined as the number
of sources in a circle with 4 degree at a given direction. Blue areas are the
areas with source density zero which are supposed to be filled with the
VCS3 observing campaign.
