General Comments. ( Brief data summary and scan listing )
18cm experiment observed on 7 Mar 2005. Data rate was 256 Mbps (4 X 8 MHz subbands, dual polarization, two-bit sampling). The target source 'NGC4335' was calibrated using the phase-reference source 'J1217+5835'. 'NGC2329', 'NGC5490', 'NGC5141' and 'NGC315' were self-calibrated. 'DA193', '3C286' and 'OQ208' were also observed as calibrators/fringe finders.
8 stations participated. Torun had BBC #3 unlocked, which means RCP data in IF 2 were lost - these data have already been flagged. No fringes seen to Nt in IF 2 LCP (corresponds to BBC #4) - these data will need to be flagged. The Lovell telescope (Jb) uses a longer phase-reference cycle than the other stations; off-source scans will need to be flagged. Effelsberg was stopped due to snow for several periods. Further comments on missing data can be found on the station feedback page.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.91 . ERI* = 0.93 . (EF=0.92(0.99*), WB=1, JB=1, ON=1, MC=0.99, TR=0.88, CM=1, NT=0.88)

Plots of the autocorrelations
Comments.
Mc: persistent RFI in IF 2.
On: Some intermittent RFI in IF 2.
Ef: Weak but persistent RFI in IF 1.
Cm: Only IFs 1 and 2 contain useful data, due to limited bandwidth of MERLIN microwave link.
