scan listing

X band phase-referencing experiment, observed on 28 November 2006. Data rate was 256 Mbps (4 X 8 MHz subbands, dual polarization, two-bit sampling). The target source 'ARP220' was calibrated using the phase-reference source 'J1532+2344'. 'J1516+1932' was also observed for phasing up WSRT and VLA27. 'J1613+3412' was the fringe finder.
18 stations participated. No fringes were found to Gb.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.84 . ERI* = 0.84 .
(EF=0.95, ON=1, MC=0.9, NT=1, WB=1, AR=0.7)

Telescope sensitivities
(the total AMP gain applied
during both a priori and self calibration; the square of this number gives the
antenna noise (SEFD) in Jy).
Comments.
Mc sensitivity is much lower than the Status table SEFD (gains are about a factor 3 higher than expected).
Wb sensitivity is a little lower than expected, probably due to poor phase stability in the tied array as reported by the station.
For all other EVN stations, sensitivity is as expected.
