The Cosmic Linear Anisotropy Solving System (CLASS) I: Overview
摘要：
宇宙线性各向异性求解系统（CLASS）是一个新的精确玻尔兹曼代码，旨在为宇宙学家提供一个更友好和灵活的编码环境。CLASS非常结构化，易于修改，并提供严格的方法来控制输出量的精度。它也比其他代码快一点。在本概述中，我们介绍了CLASS的一般原则及其基本结构。我们坚持的友好性和灵活性方面，而准确性，物理近似和性能进行了讨论，在一系列的配套文件。
英文摘要：
The Cosmic Linear Anisotropy Solving System (CLASS) is a new accurate Boltzmann code, designed to offer a more user-friendly and flexible coding environment to cosmologists. CLASS is very structured, easy to modify, and offers a rigorous way to control the accuracy of output quantities. It is also incidentally a bit faster than other codes. In this overview, we present the general principles of CLASS and its basic structure. We insist on the friendliness and flexibility aspects, while accuracy, physical approximations and performances are discussed in a series of companion papers.
