General Comments. ( Brief data summary and scan listing )
C-band e-VLBI run on 26-27 April 2008. Aggregate bitrate was 512 Mbps with 2-bit sampling, resulting in 8*8MHz subbands in both RCP and LCP. Fringe-finders were OQ208, 3C345 and 3C84. The target source Cyg X-3 was phase-referenced to J2007+4029. Additional amplitude calibrator was J2002+4725.

Third epoch ToO observations with five stations. Onsala could not joint. Cm BBC#5 unlocked -no fringes in R5. Torun had no fringes through the night, only in the last few hours. There were a series of powere failures which indirectly led to a 2s FS-UTC offset. Note that for this pipeline nominal gain and Tsys values were used for Cm, Jb, Mc and Tr; for WB the proper calibration was applied.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.74 . ERI* = 0.74 . (Cm=0.94, Jb2=1, Mc=1, Tr=0.44, Wb=1)
