Beginning of ReadMe : I/151 Precise Radio Source Positions from Mark III VLBI (Ma+ 1990) ================================================================================ Precise Radio Source Positions Determined by Mark III VLBI: Observations from 1979 to 1988 and a Tie to the FK5 Ma C., Shaffer D.B., de Vegt C., Johnston K.J., Russell J.L. <AJ, 99, 1284 (1990)> =1990AJ.....99.1284M ================================================================================ ADC_Keywords: Radio sources ; Positional data ; VLBI Description: This catalog contains observations from 600 Mark III VLBI experiments from conducted between 1979 to 1988. These experiments resulted in 237681 acceptable pairs of group delay and phase delay rate observations. These have been used to derive positions of 182 extra-galactic radio sources with typical formal standard errors less than 1 mas. The right ascension zero point of this reference frame has been aligned with the FK5 by using the optical positions of 28 extragalactic radio sources whose positions are on the FK5 system. Also included are the Mark III VLBI stations and a summary of the analysis configuration.
