广义相对论可以在强引力体系中通过自适应光学监测银河系中心围绕超大质量黑洞运行的恒星来检验。然而，不确定性的限制来源是由于大气的非等晕性和仪器像差的空间PSF的变化。加州大学洛杉矶分校的银河中心小组已经完成了一个项目，开发算法来预测凯克AO图像的PSF变化。我们已经创建了一个新的软件包（AIROPA），基于修改后的版本的Starbucks和阿罗约，它采取大气湍流轮廓，仪器像差图，和图像作为输入，并提供改进的测光和天体测量拥挤的领域。该软件包不久将公开提供。
General relativity can be tested in the strong gravity regime by monitoring stars orbiting the supermassive black hole at the Galactic Center with adaptive optics. However, the limiting source of uncertainty is the spatial PSF variability due to atmospheric anisoplanatism and instrumental aberrations. The Galactic Center Group at UCLA has completed a project developing algorithms to predict PSF variability for Keck AO images. We have created a new software package (AIROPA), based on modified versions of StarFinder and Arroyo, that takes atmospheric turbulence profiles, instrumental aberration maps, and images as inputs and delivers improved photometry and astrometry on crowded fields. This software package will be made publicly available soon.
