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.
