Brief data summary
and
scan listing
)
EK024C was observed on the 9th of March 2007. Data rate was 1 Gbps (8 X 16 MHz subbands, dual polarization, two-bit sampling). The target sources were AMS01, AMS02, AMS04 and AMS07. Phase calibrators were J1722+5856, J1722+6105 and J2005+7752. Fringe-finder used was 3C345.
9 stations were scheduled for this experiment, but Effelsberg could not observe due to hardware problems.
The EVN reliability indicator (ERI) for this experiment was
ERI = 0.87 . ERI* = 0.97 .
(EF=0, MC=0.98, ON=0.97, JB=0.98, UR=0.98, TR=0.95, NT=0.98, WB=0.97, SH=0.98)

Plenty of RFI to delete but no major problems. You can see that IF8 was unlocked at Noto (this was reported by the station).

TSYS against time
Comments.
Tsys looks generally reasonable, but Onsala has bad regions.
Telescope sensitivities

curves (the square of this number gives the antenna noise (SEFD) in Jy - the
smaller the better).

The calibration is not very good.

The calibration is reasonable in most places

The calibration source 3C345 is good, J1722+5856 is not compact, J2005+7752 looks more compact. None of the target sources are visible in the pipeline images.
