重力透镜精度测试 3 (GREAT3) 挑战赛是一项图像分析竞赛，旨在测试测量天文图像弱重力透镜的算法。该挑战赛于 2013 年 10 月开始，于 2014 年 4 月 30 日结束。该挑战赛的重点是测试对现实复杂星系形态、现实点扩散函数以及多种不同曝光组合的弱透镜测量的影响。它包括模拟的地面和空间数据。挑战的详细信息在[1]中描述，挑战网站及其排行榜可以在http://great3challenge找到。信息和 http://great3.项目。物理。伦敦大学学院。交流。分别为英国/排行榜/。
The GRavitational lEnsing Accuracy Testing 3 (GREAT3) challenge is an image analysis competition that aims to test algorithms to measure weak gravitational lensing from astronomical images. The challenge started in October 2013 and ends 30 April 2014. The challenge focuses on testing the impact on weak lensing measurements of realistically complex galaxy morphologies, realistic point spread function, and combination of multiple different exposures. It includes simulated ground-and space-based data. The details of the challenge are described in [1], and the challenge website and its leader board can be found at http://great3challenge. info and http://great3. projects. phys. ucl. ac. uk/leaderboard/, respectively.
