CASA是通用天文软件应用程序，是阿塔卡马大型毫米/亚毫米阵列（阿尔马）和卡尔G。Jansky甚大阵（VLA），也经常用于其他射电望远镜。CASA软件可以处理来自单碟、孔径合成和甚长基线干涉仪（VLBI）望远镜的数据。其核心功能之一是支持阿尔马、VLA、VLA巡天和Nobeyama 45米望远镜的校准和成像管道。本文介绍了CASA软件的基本结构，以及校准和成像CASA天文射电数据的程序的高层次的概述。CASA是由国家射电天文台（NRAO）、欧洲南方天文台、日本国家天文台和欧洲研究基础设施联合研究所（JIV-ERIC）的科学家和软件工程师组成的国际联盟在NRAO的指导下开发的。
CASA, the Common Astronomy Software Applications, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA), and is frequently used also for other radio telescopes. The CASA software can handle data from single-dish, aperture-synthesis, and Very Long Baseline Interferometery (VLBI) telescopes. One of its core functionalities is to support the calibration and imaging pipelines for ALMA, VLA, VLA Sky Survey, and the Nobeyama 45 m telescope. This paper presents a high-level overview of the basic structure of the CASA software, as well as procedures for calibrating and imaging astronomical radio data in CASA. CASA is being developed by an international consortium of scientists and software engineers based at the National Radio Astronomy Observatory (NRAO), the European Southern Observatory, the National Astronomical Observatory of Japan, and the Joint Institute for VLBI European Research Infrastructure Consortium (JIV-ERIC), under the guidance of NRAO.
