FITSH --一个用于图像处理的软件包
FITSH -- a software package for image processing
摘要：
在本文中，我们描述的软件包名为FISH的主要特点，旨在提供一个独立的环境，分析成像天文探测器获得的数据。该软件包为后续相关数据处理步骤的完整管道（包括图像校准、天体测量、源识别、测光、微分分析、低级算术运算、多图像组合、空间变换和插值等）并用于帮助解释（主要是光度测量和/或天体测量）结果。该软件包还具有基于图像减法、点扩散函数拟合和孔径光度测量的一致的光度测量实施，并提供易于使用的界面，用于比较和针对特定问题选择最合适的方法。该软件包中的这组实用程序构建在常用的UNIX/POSIX shell之上（因此该软件包的名称），因此可以利用这些环境中经常使用和记录良好的工具，并且管理大量数据相当方便。
英文摘要：
In this paper we describe the main features of the software package named FITSH, intended to provide a standalone environment for analysis of data acquired by imaging astronomical detectors. The package provides utilities both for the full pipeline of subsequent related data processing steps (incl. image calibration, astrometry, source identification, photometry, differential analysis, low-level arithmetic operations, multiple image combinations, spatial transformations and interpolations, etc.) and for aiding the interpretation of the (mainly photometric and/or astrometric) results. The package also features a consistent implementation of photometry based on image subtraction, point spread function fitting and aperture photometry and provides easy-to-use interfaces for comparisons and for picking the most suitable method for a particular problem. This set of utilities found in the package are built on the top of the commonly used UNIX/POSIX shells (hence the name of the package), therefore both frequently used and well-documented tools for such environments can be exploited and managing massive amount of data is rather convenient.
