LOFAR Status Meeting :: 09 Dec 2009

new CEP connections for a couple of stations
team to install station electronics in Potsdam
all superterp stations validated!
position of station available through GoogleMaps → link to be placed at one of the LOFAR pages

entire super terp connected → pointing will be verified today
no know electric fences at this moment
CS030 RCU 78 HBA signal is very bad
list nodes are phased out
lifs nodes are phased out
network modification completed, still resolving fall-out
estimated life-time of observations approx. 4–6 weeks, given the growing size of data-sets
solved issues:
- MAC/SAS instability
- RSP command dropped
- discrete jumps in HBA power and RMS (possibly related to bad RCU in CS030)

three-level approach
1. characterization of the tiles
2. station level
3. array calibration → selfcal at CEP
redundancy calibration
- redundant baselines measure the same visibilities
