General Comments. ( Brief data summary and scan listing )
Global spectral line experiment at 1.6 GHz, observed on 2 March 2005. Channels 2-4 were 4 MHz each, these were correlated in continuum mode (pass 1). Channel 1 was 1 MHz, RCP (pass 2) and LCP (pass 3) were produced separataly in line mode, with 512 spectral channels. This is the pass 2 pipeline.

The EVN reliability indicator (ERI) for this experiment was ERI = 1.00 . ERI* = 1.00 . (Ef=1, Wb=1, Mc=1, Nt=1, Tr=1, Hh=1, Jb=1)

Plots of the autocorrelations .
Comments.
Mc and Nt had strong RFI.

Plots of the uncalibrated amplitude and phase against time: EVN part, VLBA part .
Comments.

Plots of the uncalibrated amplitude and phase against frequency channel: EVN part, VLBA part .
Comments.
Mc and Nt RFI leaking through.

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

TSYS against time .
Comments.
Some missing Tsys for WB around 7h.

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.
Wb and Nt had somewhat lower sensitivity. Torun and Jodrell Bank (Lovell Telescope) were much less sensitive, probably due to the bad weather. (See the EVN Status Table).

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

Fringe-fit delay solutions .
Comments.
Delay jump in Noto at around 7:30.

Fringe-fit rate solutions .
Comments.

Telescope bandpasses .

Calibrated amplitude and phase against time: EVN part, VLBA part. (A priori amplitude calibration and fringe-fit solutions applied.)

Comments.
Wb and Nt had somewhat lower sensitivity. Torun and Jodrell Bank (Lovell Telescope) were much less sensitive, probably due to the bad weather. (See the EVN Status Table).
