The Precision of J2000.0 Radio Source Positions from Mark III VLBI
Published online by Cambridge University Press: 04 August 2017
Extract
A celestial coordinate frame defined by extragalactic radio sources has been developed from Mark III VLBI data. 33 000 delay and delay rate pairs acquired between August 1979 and December 1982 have been analyzed to give positions for 82 radio sources. Standard J2000.0 astronomical models were applied. 90% of the formal errors for arc lengths between sources are less than Arc lengths estimated from separate one-year data sets are consistent at the to level.
