General Comments. ( Brief data summary and scan listing )
EM117B, 6.7 GHz VLBI experiment on 2016 Feb 28. Participating telescopes were Ef, Wb, Jb, Mc, O8, Nt, Tr, Ys, Hh, Sr, Ir. You can find information on individual stations at: http://www.evlbi.org/user_guide/EVNstatus.txt.


The EVN reliability indicator (ERI) for this experiment was ERI = 0.8 . ERI* = 0.8 . (Ef=1, Wb=1, Jb=0.8, Mc=1, O8=1, Nt=1, Tr=0, Ys=1, Hh=1, Sr=1, Ir=0.9)

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

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.

TSYS against time
Comments.

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.

Fringe-fit delay solutions
Comments.
Jb LCP only seems to detect the bright calibrators. RCP is fine, but that probably means Jb wont contribute much to polarisation measurememnts. Maybe if your data reduction is more thorough you could possibly retreive the LCP too.

Fringe-fit rate solutions
Comments.

Telescope bandpasses
Comments.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Again you can see the LCP RCP difference for Jb (see FRING DELAY note)

Calibrated amplitude and phase against frequency channel
Comments.
If you jump to page 13 you can see the maser is detected very nicely on all baselines. However, no Jb. It appears to have droped out during calibration since solutions were only obtained for the bright calibrators.

Comments.
Maser is not visible in the pipeline plots because all channels (most of which have no emission) are imaged together. The masers will be seen in individual channels.
