我们提出了一套全面的模拟2dF和SDSS星系红移调查构建了一套大型的，高分辨率的宇宙学N体模拟。星表的径向选择函数和几何极限模拟了真正的巡天。星表涵盖了广泛的宇宙学，包括开放和平坦的宇宙。在所有的模型中，星系分布都是有偏的，以便近似地再现1 -10 h <$1 Mpc尺度上观测到的星系相关函数。所有模拟目录都可在http：科尔上公开查阅。我们希望这些目录是一个宝贵的援助，在开发新的算法和统计，将用于分析2dF和SDSS调查时，他们在未来几年完成。IRAS星系的PSCz巡天的模拟星表也可以在同一万维网上找到。
We present a comprehensive set of mock 2dF and SDSS galaxy redshift surveys constructed from a set of large, high-resolution cosmological N-body simulations. The radial selection functions and geometrical limits of the catalogues mimic those of the genuine surveys. The catalogues span a wide range of cosmologies, including both open and flat universes. In all the models the galaxy distributions are biased so as approximately to reproduce the observed galaxy correlationfunctiononscalesof1–10 h ¹1 Mpc.Insomecasesmodelswithavariety of different biasing prescriptions are included. All the mock catalogues are publicly available at http://star-www.dur.ac.uk/˜cole/mocks/main.html. We expect these catalogues to be a valuable aid in the development of the new algorithms and statistics that will be used to analyse the 2dF and SDSS surveys when they are completed in the next few years. Mock catalogues of the PSCz survey of IRAS galaxies are also available at the same World Wide Web location.
