MOCK 2DF AND SDSS GALAXY REDSHIFT SURVEYS

We present a comprehensive set of mock 2dF and SDSS galaxy redshift su rveys constructed from a set of large, high-resolution cosmological N- body simulations. The radial selection functions and geometrical limit s of the catalogues mimic those of the genuine surveys. The catalogues span a wide range of cosmologies, including both open and flat univer ses. In all the models the galaxy distributions are biased so as appro ximately to reproduce the observed galaxy correlation function on scal es of 1-10 h(-1) Mpc. In some cases models with a variety of different biasing prescriptions are included. All the mock catalogues are publi cly available at http://star-www.dur.ac.uk/cole/mocks/main.html. We ex pect these catalogues to be a valuable aid in the development of the n ew algorithms and statistics that will be used to analyse the 2dF and SDSS surveys when they are completed in the next few years. Mock catal ogues of the PSCz survey of IRAS galaxies are also available at the sa me World Wide Web location.
