General Comments. ( Brief data summary and scan listing )
C band phase-referencing experiment, observed on 3 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 stopped at 23:40UT for problems with the Mark5. JB lost from 04:16 to 04:50UT due to problems with bank switching on Mark5 unit.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.83 . ERI* = 0.83 . (JB=0.92, UR=1, MC=0.24, ON=1, WB=1, EF=1, TR=1, HH=1, NT=1, SH=1)
