6. LOFAR Imaging Pipeline Status

Dr George Heald (ASTRON)

26/07/2011, 12:40

In this contribution I will summarize the LOFAR imaging pipeline and give a status update. I will illustrate the performance of the various stages of the pipeline and discuss prospects for improvements and future developments.

27. Rotation Measure Synthesis

Dr Anna Scaife (DIAS)

26/07/2011, 13:20

I will describe the technique of Rotation Measure (RM) Synthesis for recovering polarisation images in Faraday Depth from multi-frequency radio data, and the parallels that exist with aperture synthesis. RM Synthesis will be a powerful tool for all pathfinder telescopes of the Square Kilometre Array (SKA), where it will be vital for magnetism science. In this talk I will describe...

8. Algorithm scaling for ASKAP and SKA

Dr Tim Cornwell (CSIRO/CASS)

26/07/2011, 14:30

Algorithms for data processing for ASKAP have been forced to change as the scale of processing has increased. Since 2007, we have implemented 4 substantial changes to our wide field imaging algorithms. We expect to require one or two more changes for full ASKAP processing. Without these changes, we could not expect to meet the resource constraints of 10000 cores each with 2GB memory. The...

19. Recent imaging results with wide-band EVLA data, and lessons learnt so far

Dr Urvashi Rau (National Radio Astronomy Observatory)

26/07/2011, 15:10

The EVLA has been producing wide-band data for science observations since Fall 2010. In this talk, I will present imaging results that demonstrate our current wide-band and wide-field imaging capability. The increased dynamic-range due to wide-band imaging (using ms-mfs) and the accuracy at which both spatial and spectral reconstructions have been made will be demonstrated via the 3C286...
