Data sets and observations
This list is anything but complete. Please add your own favourite data set if you cannot find it here!
You may also want to check MOM, in particular the LEA066 (long-baseline commissioning) project. The Solar project is LEA012.
Imaging observations of Jupiter and Saturn are LEA050.

Note: The phase centre for this observation was 03:33:59.00000 +54.34.43.0000, but the real position of the pulsar (J2000) is 03:32:59.368 54:34:43.57. This offset introduces up to 5-8 microsec delay differences on international baselines.
Corrected versions will be provided soonish!
→ NDPPP_posshift/ on widemap
This version was first shifted and then flagged. It turns out that it still has unflagged bad data in it. The reason for this is currently being investigated. At least for some of the bad points, the unshifted version had them flagged, but the new one not.
The reason for the flagging problem was a different setup of the aoflagger.overlapperc and aoflagger.timewindow parameters.
done: new NDPPP run with better flagging and with phase shift → NDPPP_posshift_new

The observation was scheduled for 12 hours around transit using all available Dutch stations (16CS+9RS) and all international stations. Specification summary: HBA dual 110-190MHz 1s integration time 64ch/sb subbands 77..320
Observation ID: L71716
Start time 2012-10-27 20:39:39 UTC End time 2012-10-28 08:39:39 UTC
The correlator recorded 12 h of data in all 244 sub bands.
CS302HBA0 and RS208 showed significant flagging possibly caused by (internal) interference. CS021 and CS103 have very low sensitivity. CS024, CS101, CS302 and CS501 have low sensitivity.
For more details, the summary plots can also be found on: https://proxy.lofar.eu/inspect/HTML/71716/index.html
Data recording: No issues.
Data processing: The data has been pre-processed using settings provided by the PI.
Archiving: The raw and processed data will be transferred directly to Juelich by Richard Fallows.
