scan listing

EJ016A, L-band VLBI experiment on 2016 March 03. Participating telescopes were Jb, Wb, Ef, Mc, O8, T6, Ur, Tr, Sv, Zc, Bd, Sr. 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 .
(Jb=1, Wb=1, Ef=1, Mc=1, Nt=0, O8=1, T6=0, Ur=1, Tr=1, Sv=1, Zc=1, Bd=1, Sr=1)

TSYS against time
Comments.
IF 8 for Sv, Zc and Bd did not make it into the data. Also, due to unphysical TSYS values derived from the station log from Sv we had to fudge IF 1 in both RCP and LCP to match the others (I simply re-used IF 2 TSYS values). You could just flag IF1 if it looks suspicious to you, but, lookng at the FRING results of Sv - IF1 seems ok to use. IFs 8, as mentioned earlier, didnt make it as far as fring (Sv, Zc, Bd).
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.
You can see some messy results at all stations at about 21:30 UT. This is just because the refant, Sr, must have had bad solutions. It should be fine on non-Sr baselines.

The bright calibrator is seen nicely, the reference source is also imaged (see ej016a_J0813+25_ICLN_2.pdf). You should get good results with these data!
