Mock 2dF and SDSS Galaxy Redshift Catalogues

by Shaun Cole, Steve Hatton, David Weinberg and Carlos Frenk

For information on the construction and properties of the mock 2dF and SDSS catalogues, please select from the following items.

Use the tables below to select and download the mock 2dF and SDSS galaxy redshift catalogues. Hold shift and then click on the required model. The SDSS catalogues are 24 Mbytes and the 2dF SGP and NGP catalogues 5.4 Mbytes and 2.7 Mbytes respectively. The catalogue file format is that of a bigendian fortran unformatted file and can be read with this fortran subroutine. Note that a tabulated selection function is available for each of the mock catalogues.

Standard Models

All the models in this section are biased using bias Model 1 and have their selection functions derived from the same "non-evolving" luminosity function.

Variations

The following mock catalogues are for only three selected cosmologies but with various methods of biasing, choice of selection function etc. All models are normalized to the abundance of rich galaxy clusters.

Multiple Realizations

The following mock catalogues are for a single cosmology and a single biasing prescription, ie (E3S) the TauCDM model. There are 10 different realization each based on an entirely independent N-body simulation. (NB the first two of these realizations are already listed in the table above which includes more than the single biasing prescription.)
