We reproduce the galaxy clustering catalogue from the SDSS-III BaryonOscillation Spectroscopic Survey Final Data Release (BOSS DR11&DR12)with high fidelity on all relevant scales in order to allow a robustanalysis of baryon acoustic oscillations and redshift space distortions.We have generated (6000) 12 288 MultiDark PATCHY BOSS (DR11) DR12 lightcones corresponding to an effective volume of ?192 000[h-1 Gpc]3 (the largest ever simulated volume),including cosmic evolution in the redshift range from 0.15 to 0.75. Themocks have been calibrated using a reference galaxy catalogue based onthe halo abundance matching modelling of the BOSS DR11&DR12 galaxyclustering data and on the data themselves. The production follows threesteps. First, we apply the PATCHY code to generate a dark matter fieldand an object distribution including non-linear stochastic galaxy bias.Secondly, we run the halo/stellar distribution reconstruction HADRONcode to assign masses to the various objects. This step uses the massdistribution as a function of local density and non-local indicators(i.e. tidal field tensor eigenvalues and relative halo exclusionseparation for massive objects) from the reference simulation applied tothe corresponding patchy dark matter and galaxy distribution. Finally,we apply the SUGAR code to build the light cones. The resultingMultiDarkPATCHY mock light cones reproduce the number density, selectionfunction, survey geometry, and in general within 1σ, for arbitrarystellar mass bins, the power spectrum up to k = 0.3 h Mpc-1,the two-point correlation functions down to a few Mpc scales, and thethree-point statistics of the BOSS DR11&DR12 galaxy samples.
