Brief data summary
and
scan listing
)
Some general comments here, e.g.: L band full polarization experiment, observed on 1 March 2008. Data rate was 512 Mb/s (8 X 8 MHz subbands, dual polarization, two-bit sampling). The target source '0836+710' and '0859+681' was used as a calibrator. '4C39.25' and '3C345' were observed as fringe finders.
10 stations participated. Nt was mispointing due to a fault in the subreflector position. Some other time was lost due to strong winds at Jb, Cm, On, Tr.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.73 . ERI* = 0.88 .
(JB=0.67 CM=0.77 EF=0.91 ON=0.43 NT=0 UR=1 SH=1 TR=0.54 MC=1 WB=1)

Comments.
Some strong time dependent RFI vissible. Not noticed in the PI letter earlier: CM IF 4 RR. 96 pages
plots of the uncalibrated amplitude and phase
against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied. More editing will be needed. 32 pages

TSYS against time
Comments.
The occurence and severeness of the RFI could be derived from some plots (see eg. MC, IF 1 and IF 2 of WB etc)
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.
In areas clear of RFI, no major differences from the expected SEFD
Fringe-fit phase solutions
(including Parallactic
Angle correction).
