iCosmo：一个交互式宇宙学软件包
iCosmo: an Interactive Cosmology Package
摘要：
目的：交互式软件包iCosmo，旨在进行宇宙学计算的描述。方法：iCosmo是一个软件包，用于对低红移宇宙进行交互式宇宙学计算。计算距离措施，物质功率谱，和增长因子支持任何值的宇宙学参数。它还计算了几个宇宙学探测器，如宇宙剪切，重子声学振荡和Ia型超新星的观测量。这些可观测量的相关误差可以从定制的测量中得出，或者从与当前或计划的仪器相对应的预设值中得出。该代码还允许使用Fisher矩阵计算宇宙学预测，可以将不同的调查和宇宙学探测结合起来。该代码是用IDL语言编写的，因此受益于该语言提供的方便的交互式功能和科学库。iCosmo也可以作为一个引擎，以批处理模式进行宇宙学计算，并为进一步的宇宙学模块的开发提供了一个方便的自适应平台。凭借其广泛的文献，它也可以作为教学和宇宙学领域的新人的有用资源。结果：iCosmo软件包通过各种示例和命令序列进行了描述。该代码可在http://www.icosmo.org上免费获得，并附有交互式Web界面，是宇宙学倡议的一部分，这是宇宙学资源的公共档案。
英文摘要：
Aims: The interactive software package iCosmo, designed to perform cosmological calculations is described. Methods: iCosmo is a software package to perform interactive cosmological calculations for the low redshift universe. Computing distance measures, the matter power spectrum, and the growth factor is supported for any values of the cosmological parameters. It also computes derived observed quantities for several cosmological probes such as cosmic shear, baryon acoustic oscillations and type Ia supernovae. The associated errors for these observables can be derived for customised surveys, or for pre-set values corresponding to current or planned instruments. The code also allows for the calculation of cosmological forecasts with Fisher matrices which can be manipulated to combine different surveys and cosmological probes. The code is written in the IDL language and thus benefits from the convenient interactive features and scientific library available in this language. iCosmo can also be used as an engine to perform cosmological calculations in batch mode, and forms a convenient adaptive platform for the development of further cosmological modules. With its extensive documentation, it may also serve as a useful resource for teaching and for newcomers in the field of cosmology. Results: The iCosmo package is described with various examples and command sequences. The code is freely available with documentation at http://www.icosmo.org, along with an interactive web interface and is part of the Initiative for Cosmology, a common archive for cosmological resources.
