kapteyn包：天文应用程序的python模块
kapteyn的Python项目详细描述
kapteyn包是python模块的集合。 以及kapteyn计算机组开发的应用程序 荷兰格罗宁根大学天文研究所。这个 该软件包的目的是为开发 使用python的天文应用程序。
该软件包既适用于经验不足的用户，也适用于经验丰富的用户。 为这两个组提供了开发人员和文档。这个 文件还提供了有关天体的深入章节 变换、谱平移和非线性最小二乘拟合。
软件包最重要的功能：
- The handling of spatial and spectral coordinates, WCS projections and transformations between different sky systems. Spectral translations (e.g., between frequencies and velocities) are supported and also mixed coordinates. (Modules wcs and celestial, Module wcs uses Mark Calabretta’s WCSLIB which is distributed with the package.)
- Versatile tools for writing small and dedicated applications for the inspection of FITS headers, the extraction and display of (FITS) data, interactive inspection of this data (color editing) and for the creation of plots with world coordinate information. (Module maputils) As one example, a gallery of all-sky plots is provided.
- A class for the efficient reading, writing and manipulating simple table-like structures in text files. (Module tabarray)
- Utilities for use with matplotlib such as obtaining coordinate information from plots, interactively modifiable colormaps and timer events (module mplutil); tools for parsing and interpreting coordinate information entered by the user (module positions).
- A function to search for gaussian components in a profile (module profiles) and a class for non-linear least squares curve fitting (module kmpfit)
