Light cones were constructed by talking lines-of-sight through the Millennium Simulation halo and galaxy catalogue box at increasing redshifts, using code written by Manfred Kitzbichler and described in Kitzbichler & White 2007. The semi-analytic galaxy catalogue used for all cones is the model of Croton et al. 2006, with the addition of the dust prescription given in Kitzbichler & White 2007.
Three sets of light cones are available, differing primarily in their magnitude limits, redshift depth, and sky coverage. Common to all cones are the following fields:
•galaxy type (central or satellite)
•galaxy/halo position and velocity
•halo virial properties (Mvir, Vvir, Rvir)
•halo spin and velocity dispersion
•total and bulge stellar mass
•cold, hot and ejected gas mass
•black hole mass
•star formation rate
•hot halo cooling and AGN heating rates
•apparent and absolute (total and bulge) magnitudes in DEEP2 (BRIK), SDSS (ugriz), and Cousins (BVRIK) filters, for each galaxy (14 filters in all).
Note that:
•All magnitudes are in the AB system.
•Absolute magnitudes for DEEP2 and SDSS filters were calculated from the apparent magnitudes using the appropriate version of Mike Blanton's kcorrect. For some cones the kcorrections may not be valid across the entire redshift range. In such cases, please use the Cousins absolute magnitudes or do your own kcorrections from the apparent magnitudes.
•All files are in binary format and are readable via the included IDL script.
