我们展示了开源和社区开发的Python包的第一个公共版本(v0.2)，Astropy。此包向社区提供核心的天文学相关功能，包括支持特定领域的文件格式，例如灵活的图像传输系统(FITS)文件、虚拟天文台(VO)表和常见的ASCII表格式、单位和物理量转换、特定于天文学、天文坐标和时间转换的物理常数、世界坐标系(WCS)支持、用于表示网格和表格数据的通用容器以及宇宙学转换和转换的框架。正在积极开发重要的功能，例如模型拟合框架、VO客户端和服务器工具以及光圈和点扩散函数(PSF)光度测量工具。核心开发团队正在积极地对当前的代码库进行添加和增强，我们鼓励任何有兴趣的人参与未来Astroy版本的开发。
We present the first public version (v0.2) of the open- source and community- developed Python package, Astropy. This package provides core astronomy- related functionality to the community, including support for domain- specific file formats such as flexible image transport system (FITS) files, Virtual Observatory (VO) tables, and common ASCII table formats, unit and physical quantity conversions, physical constants specific to astronomy, celestial coordinate and time transformations, world coordinate system (WCS) support, generalized containers for representing gridded as well as tabular data, and a framework for cosmological transformations and conversions. Significant functionality is under active development, such as a model fitting framework, VO client and server tools, and aperture and point spread function (PSF) photometry tools. The core development team is actively making additions and enhancements to the current code base, and we encourage anyone interested to participate in the development of future Astropy versions.
