General Comments. ( Brief data summary and scan listing )
L band phase-referencing experiment, observed on 7 June 2007. Data rate was 512 Mbps (8 X 16 MHz subbands, dual polarization, two-bit sampling). The target sources were calibrated using the phase-reference sources 'J0808+4950', 'J0801+4401' and 'J0932+5306'. '0234+285' and '4C39.25' were also observed as calibrators. '0234+285' was the fringe finder.
7 stations participated. Tr has problems with IF7 & 8 (RR). Wb and On reported lot of RFI. Ef lost a few scans because of "long azimuth driver/cable unwrap", pointing scans and thunderstorms.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.89 . ERI* = 0.91 . (JB=1, NT=1, Mc=1, Tr=0.875, ON=1, Wb=0.962, Ef=0.792)

TSYS against time
Comments.
12 pages. TY1 table, each IF/pol on a separate plot.

Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).
Comments.

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
12 pages. CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2.
