摘要:

费歇尔矩阵是现代宇宙学预测的支柱。我们描述了Fisher 4Cast软件:一个通用的,易于使用的Fisher矩阵框架。它是开源的,经过严格的设计和测试,包括一个图形用户界面(GUI),具有自动LATEX文件创建功能和点击Fisher椭圆生成功能。Fisher 4Cast是为了便于扩展而设计的,虽然是用Matlab编写的,但很容易移植到开源替代品,如Octave和Scilab。在这里,我们使用Fisher 4Cast提出新的3-D和4-D可视化的预测景观,并调查未来的宇宙学调查的增长和曲率的影响。自2008年5月以来,早期版本已在http://www.cosmology.org.za上提供,第一年下载量为750次。2.2版与本文一起公开,包括一个快速入门指南和用于生成本文中图形的代码,希望它对宇宙学和更广泛的科学界有用。

英文摘要:

The Fisher Matrix is the backbone of modern cosmological forecasting. We describe the Fisher4Cast software: a general-purpose, easy-to-use, Fisher Matrix framework. It is open source, rigorously designed and tested and includes a Graphical User Interface (GUI) with automated LATEX file creation capability and point-and-click Fisher ellipse generation. Fisher4Cast was designed for ease of extension and, although written in Matlab, is easily portable to open-source alternatives such as Octave and Scilab. Here we use Fisher4Cast to present new 3-D and 4-D visualisations of the forecasting landscape and to investigate the effects of growth and curvature on future cosmological surveys. Early releases have been available at http://www.cosmology.org.za since May 2008 with 750 downloads in the first year. Version 2.2 is made public with this paper and includes a Quick Start guide and the code used to produce the figures in this paper, in the hope that it will be useful to the cosmology and wider scientific communities.
