SKA Calibration and Imaging Workshop, 2016

The workshop has completed! Our thanks to all the participants for making it a very vibrant and scientifically useful workshop. The "official" summary of the workshop is available here.

Here is Steve Myers take on the workshop.

CALIM Workshops are meetings to discuss state-of-the-art in interferometric calibration and imaging algorithms/techniques. The next in this series of workshops will be held at NRAO, Socorro, Oct. 10-14th., 2016

Dates: Oct. 10th - 14th, 2016.

Meeting will begin Monday and go through Friday. We are planning on 5 full days.

There will be a meeting reception on Sunday, Oct 9 and a workshop dinner during the workshop.

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

Host: NRAO

Sponsored by: NRAO, SKA Organisation

Presentations at this workshop are by invitation only. The number of participants is limited to about 50 people.

Scientific Program

The final program along with the links to all but one presentation for CALIM2016 is here.

Registration (there is no registration fee for this meeting)

Registration for this workshop is now closed.

List of participants

The current list of registered participants is now available here

The workshop has now completed. Total of 60 people registered and 55 came to Socorro. Those who could not were due to sickness, family engagements or visa problems. Number of people attending the workshop in addition to the registered participants was in the 65-70 range (going by the capacity of the venue).

Focus and goals of the workshop

The CALIM series of workshops 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. We invite presentations on the following topics:
  • Wide-field imaging
  • Wide-band imaging
  • WB, WF, Full-polarization imaging
  • Aperture arrays
  • Dense arrays
  • Sparse arrays
  • Phased array feeds
  • Calibration and imaging algorithms
  • RFI removal/mitigation algorithms
  • Ionospheric calibration
  • Simulation of observations
  • Scaling of calibration and imaging algorithms
  • Pipelined processing
  • Heuristics for calibration and imaging
  • Run-time estimates/costs
  • Computational costs of algorithms
  • Cost vs accuracy equations
  • Use of supercomputers, accelerators, and special purpose hardware
  • Cloud computing options
  • Algorithmic and computational architecture for large surveys
  • Compressive Sampling and Bayesian algorithms for calibration and imaging

Participation is by invitation only and will be limited to about 50. Late registrations and abstracts may be accepted by the LOC & SOC if space is available in the program.

Travel Information

Participants should make their own travel arrangements for arriving in Socorro. The closest airport to Socorro is Albuquerque (ABQ), which is about 70 miles north of Socorro. If you are driving see the directions provided below. having a rental car is convenient and preferred. We encourage attendees who rent cars to car-pool from the Albuquerque airport. Several car rental options are available from Albuquerque airport.

Other Events

Socorro will also be hosting the "Coexisting with Radio Frequency Interference" (RFI2016) conference this year from Oct. 17th. to 20th. This is the week after the CALIM meeting. Please visit the conference web site ( for more details.

Driving Instructions
