Five sources, never previously observed with the VLBA, were added to the schedule, two scans per source. All of them have been detected. Their positions were determined with 2–5 mas accuracies. Results of this experiment have been published at L. Petrov, C. Phillips, A. Bertarini, A. Deller, S. Pogrebenko, A. Mujunen, "The use of the Long Baseline Array in Australia for precise geodesy and absolute astrometry", Publications of the Astronomical Society of Australia, 26(1), 75-84, 2009. DOI: 10.1071/AS08030, Full text (PDF, 308Kb).This experiment has proved the concept. Detailed discussion related to the v230 experiment can be found here. Other details can be found here.
Correlated: 1564 Number of potentially recoverable observations: 1222 Number of potentially good observations with QC 5-9: 1223 Number of used observations: 1159 ( 94.84%) Quick look at v271a 127 scheduled 126 observed 118 detected Detection rate is 93%. Resolving ambiguities was a bigger problem for this experiment, but it went through. It is difficult to tell anything about astrometric quality, since two few baselines were processed.

The second preliminary catalogue of source positions was derived from data analysis of the experiment. The catalogue is available here.
