Brief data summary
and
scan listing
)
L-band phase-referencing experiment, observed on 28 Feb 2008. Data rate was 1 Gbps (8 X 16 MHz subbands, dual polarization, two-bit sampling). The target sources were calibrated using the phase-reference sources 'J1225+1253' and 'J1332+4722'. '3C345' was the fringe finder.
10 stations participated. Wb IF8 fell outside the available bandwidth, and has been flagged. Due to strong interference, Wb's IF2 cross-pol signal is strong. Most of Sh data are lost due to recording problems. Nt reported that the lower side band of the bbc#8 was in overflow for the whole experiment.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.79 . ERI* = 0.79 .
