General Comments. ( Brief data summary and scan listing )
C band phase-referencing experiment, observed on 12 Jun 2008. Data rate was 1 Gbps (8 X 16 MHz subbands, dual polarization, two-bit sampling). The target source 'IRAS1929' was calibrated using the phase-reference source J1941-0511. '3C286' and '2134+004' were observed as fringe finders and additional calibrator.
11 stations participated. Cm was affected by recording problems for the whole experiment and Nt was partially affected.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.78 . ERI* = 0.79 . (JB=1, EF=0.75 , CM=0, WB=0.875 ,ON=1.0, MC=1.0, NT=0.62 ,TR=1 ,UR=0.78 ,SH=0.58 ,HH=1 )
