This dataset contains 24 pencil beam mock catalogues of a deep field of 1.4 times 1.4 square degrees created by
Manfred Kitzbichler for the COSMOS collaboration.
These catalogues were created from a galaxy catalogue similar but not identical to the
MPAGalaxies..DeLucia2006a. galaxy catalogue.
Whereas the same parameters were used for the galaxy formation algorithm , the halo merger trees were different.
See DeLucia & Blaizot 2007 for a description of the different merger tree definitions.
For this reason no links are provided to the main galaxy catalogues.
But since these catalogues have been quite widely used we felt it of interest to publish them in the database.
Some of the papers using these catalogues are:
The data set is distributed over 24 tables, named COSMOS_012_000, COSMOS_012_001, ..., COSMOS_012_111
and versions with 120 and 201 iso 012. See also the menu bar on the query page.
These represent 8 different directions of the basis cone and 3 different origins.
They contain Johnson magnitudes plus some physical information.
