We present a new approach to improve the forward modeling of reconstruction method for the Baryonic Acoustic Oscillations study. We use probability information from the Halo Occupation Distribution (HOD) function of a given type of galaxies in order to enhance the estimation of the local density field of the dark matter. We couple the HOD information to the Conditional Luminosity Function of red type galaxies to exemplify the possibility to enhance the connection between dark matter and a well‐established tracer as Luminous Red Galaxies (LRGs). However, the main purpose is to enhance this connection for more complicated tracers as Emission Line Galaxies (ELGs) and quasars (QSOs).
