论文摘要

CASA是常见的天文学软件应用程序，是Atacama大毫米/亚毫米阵列（ALMA）和Karl G. Jansky的主要数据处理软件，非常大（VLA），也经常用于其他射电望远镜。 CASA软件可以处理单次，孔径合成和非常长的基线干涉仪（VLBI）望远镜的数据。它的核心功能之一是支持ALMA，VLA，VLA Sky Survey（Vlass）和Nobeyama 45m望远镜的校准和成像管道。本文介绍了CASA软件基本结构的高级概述，以及CASA中校准和成像天文数据的程序。 CASA由国际科学家和软件工程师联盟开发，位于国家射电天文台（NRAO），欧洲南方天文台（ESO），日本国家天文台（NAOJ）和VLBI欧洲欧洲研究基础设施联盟联合会（JIV-ERIC）（JIV-ERIC）下，在NRAO的指导下。

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 (VLASS), and the Nobeyama 45m 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 Astronomical Observatory (NRAO), the European Southern Observatory (ESO), the National Astronomical Observatory of Japan (NAOJ), and the Joint Institute for VLBI European Research Infrastructure Consortium (JIV-ERIC), under the guidance of NRAO.
