LOFAR Status Meeting :: 09 Dec 2009
Notes from the meeting
LOFAR roll-out update (G. Heald)
- 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
Observatory status update (M. Brentjens)
- 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)
Wijnholds - Status HBA station calibration
- three-level approach
- characterization of the tiles
- station level
- array calibration → selfcal at CEP
- redundancy calibration
- redundant baselines measure the same visibilities
