Brief data summary

scan listing

C-band e-VLBI run on 25-26 June 2007. Aggregate bitrate was 256 Mbps with 2-bit sampling, resulting in 4*8MHz subbands in both RCP and LCP. Fringe finder and D-term calibrator was 3C48. Cyg X-3 was phase-referenced to J2007+4029. Additional potential calibrators wers observed for a short time. Sterted ~1 hour late because initial attempts to run the project at 512 Mbps. The run went very smoothly overnighti at 256 Mbps. There were some Mk5/SU problems, especially in the last third of the experiment. Note that for Cm, Jb and On nominal SEFDs and system temperatures were used. Cm has no Tsys measurements. In Jb it seems that the calibration diode was not fired or it was not connected. The Onsala calibration data are being reprocessed.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.65 . ERI* = 0.65 .
(Cm=1, Jb=1, ON=1, Mc=1, On=1, Wb=1)
