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 Arecibo, Onsala, Torun and Westerbork. There were 2x4 MHz channels recorded: one in LCP and one in RCP.

Plots of the autocorrelations .
Comments.
On: weak RFI near 1459 MHz.

Plots of the uncalibrated amplitude and phase against time .
Comments.
Before 10:30 UT clock-searching jobs were done. Data between 11:00-11:30 UT were bad and flagged.

Plots of the uncalibrated amplitude and phase against frequency channel .
Comments.
Calibrator is detected.

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).
Comments.

Fringe-fit delay solutions .

Fringe-fit rate solutions .

Comments.

Amplitude corrections applied to a priori calibrated and fringe-fitted data by self-calibration.
J0645+213: postscript , or text file .
Comments.

Telescope sensitivities (the total AMP gain applied during both a priori and self calibration; the square of this number gives the antenna noise (SEFD) in Jy).
Comments.
The sensitivity of the stations was as expected.
