GREAT3
The third GRavitational lEnsing Accuracy Testing challenge.
The third GRavitational lEnsing Accuracy Testing challenge, or GREAT3, is a blind data challenge held by the world-wide weak lensing community to test weak lensing measurement algorithms.
With several major astronomical surveys beginning to make large-scale cosmological weak lensing measurements in 2013 in order to better understand our cosmological model (including the mysterious dark matter and dark energy), this challenge will play an important role in identifying promising measurement algorithms and quantifying their performance.
The challenge itself will occur in 2013, with preparations actively underway now. For more information about the challenge under development, see the links above.
