SKA Calibration and Imaging Workshop, 2009

The fourth in the series of SKA Calibration and Imaging Workshops has successfully concluded. It was hosted by NRAO at the Socorro Science Operation Center, New Mexico.

Dates: March 30 - April 02, 2009. General discussions on Friday, April 03, 2009.

Venue: Pete V. Domenici Science Operations Center (formerly AOC), Socorro, New Mexico, USA

Host: NRAO

Sponsored by: NRAO, SKA SPDO

Talks at this workshop are by invitation only and there will be no poster presentations. The number of participants is limited to about 50 people.

Focus and goals of the workshop

This workshop focuses on progress in algorithms, software and computing aimed at solving the challenges in calibration and imaging requirements of the SKA, its pathfinders and other major new radio telescopes such as EVLA, ALMA, LOFAR, ASKAP, MeerKAT, MWA, LWA, and eMERLIN. The main part of the meeting (first 4 days) will involve discussions and presentation mainly by algorithm and software developers.

The 5th day of the meeting is intended for more general discussions involving broader set of people who may not be directly involved in algorithms and software development. We will post more details about activities for this day on this page in a few weeks.


For this workshop, in addition to discussions on topics listed below, presentations and discussions related to the required computing, use of specialized hardware for computing etc. are also highly encouraged.

  • Wide field imaging
  • Wide band imaging
  • Aperture arrays
  • Phased array feeds
  • Calibration and Imaging algorithms
  • Ionospheric calibration
  • Simulation of observations
  • Parallelization of algorithms
  • Pipelined processing
  • Computational costs of algorithms
  • Use of supercomputers, accelerators, and special purpose hardware
  • Other topics relating to calibration and imaging issues for SKA and other major new radio telescopes such as EVLA, ALMA, LOFAR, ASKAP, MeerKAT, MWA, LWA and eMERLIN.


Attendees will be responsible for their own travel and accommodation expenses. Morning and afternoon tea and lunch will be provided.
