The EVN ToO observations ran at C band with 1024 Mbps recording rate (16 channels, 16 MHz/channel, 2bit sampling, dual polarisation) on 22 Mar 2010. The participated telescopes were Ef, Cm, Jb1, Kn, Mc, On, Nt, Tr, Wb and Ys. The target XTEJ1752-223 was calibrated by the phase-referencing source J1755-2232. The source NRAO530 and J1824+1044 were also observed as the fringe finder and bandpass calibrators.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.8 . ERI* = 0.8 .
YS had no observations due to a problem with main moter bus. (Cm=1, Kn=1, Jb1=1, Mc=1, Ef=1, On=1, Wb=1, Tr=1, Nt=1, Ys=0)
Plots of the autocorrelations
Comments.
JB: auto-correlation plots looked wrong because its sampler statistics was too poor to get proper correction factors by 2bitVV. Cm & Kn: signal in IF 3 and 4 only.

against time

Plots of the uncalibrated amplitude and phase

Comments.
Strong fringes were found to all the stations.

TSYS against time
Comments.
Telescope sensitivities
from the a priori TSYS and Gain
curves (the square of this number gives the antenna noise (SEFD) in Jy - the
smaller the better).
Comments.
Fringe-fit phase solutions
(including Parallactic
Angle correction).

Fringe-fit delay solutions
Comments.
J1755-2232 was the phase-referencing calibrator. SOLINT= 2 min.
