General Comments. ( Brief data summary and scan listing )
This was an L-band eVLBI spectral line experiment observed on 22 September 2004. Participating stations were Cambridge, Onsala, Torun and Westerbork. There were 2x1MHz channels recorded: one in LCP and one in RCP. Crosshand correlations were not produced.

Plots of the autocorrelations .
Comments.
Weak RFI at Onsala and Westerbork. (Source naming is not correct on the plots.)

Plots of the uncalibrated amplitude and phase against time .
Comments.
All sources detected.

Plots of the uncalibrated amplitude and phase against frequency channel .
Comments.
MASER lines are clearly present in the target spectrum.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel (not available) .
Comments.

TSYS against time .
Comments.
Note that a preliminary ANTAB file was used to process the data.

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.
Tr: the gain value supplied by the station was wrong. Tried to improve by guessing (see notes in the ANTAB file). The station gains can be compared to the EVN Status Table).

Fringe-fit phase solutions (including Parallactic Angle correction).
