Data sets

Important dates (changes of data formats etc)

  • Raw voltages in fly's eye mode are correct from 28 Oct 2011 onwards (L2011_32955).
  • DE601 clock offset before ca. 30 Oct 2011 is 1.1 microsec, 2.2 microsec in L2011_33159, and fixed since L34671 11/12 November 2011.
  • Ordering of antennas in MS as written/read by LofarStMan: Ant1-Ant2 with
  • Ant1⇐Ant2 until at least JD 55742.6, 29th June 2011, then swapped since
  • at least MJD 55748.4, 5th July 2011. Swapped back when reading with new LofarStMan version from 2/3 Nov 2011 (2 on cep, 3 on widemap) onwards. See here.

L2011_25128 (TauA)

interferometry + beam-formed, 2+2 stations, 16 subbands, problems with beam-formed raw voltages

Antennas: 0=FR606, 1=RS106, 2=RS208, 3=UK608

Due to a bug in the software writing the raw voltage data, some of the files are corrupted. Incoherent Stokes and visibilities do not seem to be affected.

Bad raw data are:

  • 0=FR606 (X: subband 0 bad, Y: subband 1 bad; all bad in first second)
  • 3=UK608 (all bad)

The other antennas are fine.

comparison between raw voltages and visibilities: generally okay, that means raw voltages in fly's eye mode are working now, but there seem to be problems in the visibilities whenever same samples within the integration are flagged (happens very often in antenna 4 = DE602HBA)

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

deleted old versions, including combined versions

FIXME: redo the combining and phasing up and then continue with XY offsets and conversion to circular

Still working on this!

voltages have about 5% fraction flagged, visibilities and incoherent sum not

Weights (at least of autocorrelations) in visibilities are funny. See ~/astro_wm/lofar_obs_wm/L2012_60895/

L2012_71716 (TauA)

From email

Date: Tue, 30 Oct 2012 10:53:39 +0100
From: Wilfred Frieswijk frieswijk [at] astron [dot] nl

General notes:

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

Observing date:

Start time 2012-10-27 20:39:39 UTC End time 2012-10-28 08:39:39 UTC

Performance of the system:

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.
