Two all-sky light cones created using the Maraston (2005) stellar populations
resides in the table cones.AllSky_001 and cones.AllSky_002.
They were constructed by replicating the Millennium simulation
box (500Mpc/h on a side) with no additional transformations applied. The catalogues are limited to an apparent observer-frame
AB magnitude of (SDSS) i< 21.0 and includes apparent observer-frame magnitudes for 9 filters: SDSS u, g, r, i, z and VISTA Y, J, H,
Ks. The algorithm is equivalent to the one used for the all sky map in
MPAMocks..Blaizot2006_AllSky_PT_1.
The differenece between the light cones is their obseration point. For 001 ths is at the origina of the simulation box, for 002 it lies at the
center, X=Y=Z=250/h.
