| Abstract: |
The VSOP mission is a Japanese-led project to image radio sources with sub-mas resolution using an orbiting 8-m telescope, HALCA, with a global array of telescopes. About 25% of the observing time was devoted to a survey at 5 GHz of the brightest, compact AGN. Using a complete sample of AGN's with δ > −44° which overlapped VLBA observations, we determined the statistical properties of the angular size and brightness temperature distribution by analyzing the observed correlated amplitude versus projected radio spacing. We find that 80% of the radio cores have an angular size in the range 0.03 < 0.8 mas and that 10 ± 5% of the cores have a brightness temperature > 1013 K. |
