General Comments. ( Brief data summary and scan listing )
C band phase-referencing experiment, observed on 26 Feb 2009. Data rate was 1 Gbps (16 X 16 MHz subbands, dual polarization, two-bit sampling). The target sources IRAS07251-0248 was calibrated and successfully detected using the phase-reference sources J0730-0241. J0854+2006, 4C39.25, and 3C286 were also observed as calibrators and fringe finders.

11 stations participated. Ur lost fringes due to a problem of MK5A IO board. On lost the first 4.5 hour data because the disk was damaged by a burnt chip during playback process.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.69 . ERI* = 0.69 . (Jb = 1, Cm = 1, Kn = 1, Ef = 1, Wb = 1, On = 0.25, Mc = 1, Nt = 1, Tr = 1, Ur = 0, Sh = 1)
