4cm experiment, observed on 16 June 2007. Data rate was 4Mbps (4 X 2 MHz subbands, dual polarization, two-bit sampling). The target source was calibrated using the sources '3C48' and 'J1743-0350'. 'J1751+09' was also observed as a calibrator. '3C345' and '3C286' were the fringe finders. The reference antenna is EF.
8 stations participated, but Onsala didn't observe because of an antenna hardware problem.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.75 . ERI* = 0.75 .
