论文摘要
我们提出了第一个公共代码,用于计算微透析事件期间发生的天体中心转移。该计算基于轮廓集成方案,涵盖了具有任意肢体变暗曲线的有限源的单元和二进制镜头。这允许对有限源大小在天体二进制微透镜中的影响进行一般详细研究。新代码嵌入了VBBinaryLensing版本的3.0版中,该版本提供了一种强大的计算工具,可用于广泛研究当前调查和未来空间任务的微透镜数据。
We present the first public code for the calculation of the astrometric centroid shift occurring during microlensing events. The computation is based on the contour integration scheme and covers single and binary lensing of finite sources with arbitrary limb darkening profiles. This allows for general detailed investigations of the impact of finite source size in astrometric binary microlensing. The new code is embedded in version 3.0 of VBBinaryLensing, which offers a powerful computational tool for extensive studies of microlensing data from current surveys and future space missions.
