GREAT08
The GRavitational lEnsing Accuracy Testing 2008 (GREAT08) Challenge Final Workshop is incorporated into Cosmostats09.
Observed galaxy images appear distorted due to gravitational lensing and their shapes must be precisely disentangled from observational effects of sampling, convolution and noise.
The GREAT08 Challenge is open to all, and aimed at those from outside the gravitational lensing community, including statistical inference, inverse problems and computational learning. It runs from October 2008 until April 2009.
The GREAT08 Challenge contains 200 GB of simulated images, containing 30 million galaxy images. For the main competition, participants are asked to extract 5400 numbers from 170 GB of data. The competition can be accessed via the website www.great08challenge.info.
