Brief data summary

scan listing
)
C band phase-referencing e-VLBI experiment, observed on 5 Dec 2008. Data rate was 512 Mbps (4 X 16 MHz subbands, dual polarization, two-bit sampling). The target source ARP299 was calibrated using the phase-reference source J1128+5925.4C39.25, 3C84 and 3C138 were also observed as bandpass calibrators and fringe finder.
9 stations participated, including the MERLIN telescopes Cambridge 32m and Knockin, which were both recorded in the same VLBA/Mark5A terminal.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.98 . ERI* = 0.98 .
(EF=1, WB=1, JB=1, CM=1, KN=093, ON=0.96, TR=0.96, SH=1, MC=1)

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.
SEFDs: ON three times worse, JB2 two times worse, Cm twice worse than listed in the EVNStatus.txt table
