Brief data summary
and
scan listing
)
L band phase-referencing experiment, observed on 11 Mar 2007. Data rate was 1 Gbps (16 X 16 MHz subbands, dual polarization, two-bit sampling). The target sources were calibrated using the phase-reference sources 'J1428+3259'. 'J1422+3223' was also observed as calibrator. 'J1407+2827' was the fringe finder.
10 stations participated. Mc used a corrupted disk, lost scans 1 to 22 (21:30-22:32UT). The Mk5 computer at Ur died from 2:06-2:10UT.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.97 . ERI* = 0.97 .
(JB=1, UR=0.99, MC=0.85, ON=1, WB=1, EF=1, TR=1, HH=1, NT=1, SH=1)
