Workshop on "Source Finding Challenges for ASKAP"
Thursday 29 April 2010
ATNF Marsfield Lecture Theatre
Source-finding - extracting astronomical objects of interest from images or data cubes - is of interest across a wide range of ASKAP Survey Science Projects. Automated source-finding will be part of the ASKAP on-line processing pipeline, and determining optimal source-finding algorithms will be key to getting the best scientific results.
We are holding a 1-day workshop on source-finding techniques, with the goals of
- Finding common challenges in spectral-line, continuum and polarisation source-finding for ASKAP Survey Science Projects
- Discussing existing and future solutions - what can we learn from past surveys.
- Planning the way forward for cross-SSP work on source-finding.
** NOTE ** The day before this meeting, on Wednesday, April 28, we are also holding a 3D Visualiastion demo/workshop.
Everyone is welcome to attend. The program is split into two distinct parts. The morning sessions will feature talks on either existing source finders and experience with previous surveys, or plans for source finding in future ASKAP surveys. The afternoon sessions are set aside for discussion, split between spectral-line and continuum source finding.
While the morning talks are all assigned, we welcome input into the discussion, and if you have experience or knowledge of some aspect of source finding not yet covered, please let us know and we can try to cover it in the discussion. All are welcome, however, even if you don't have much experience in this area! Please email one of the organisers (below) to register your interest.
We expect the workshop will run from approx 9:30 am to 4:30 pm. Telecon facilities will be available.
