TabCorr: Tabulated Correlation Functions

This Python module provides extremely efficient and precise calculations of galaxy correlation functions in halotools using tabulated values. It is specifically intended for Markov chain Monte Carlo (MCMC) exploration of the galaxy-halo connection. It implements the method described in Zheng & Guo (2016) of tabulating correlation functions that only need to be convolved with the mean halo occupation to obtain the full correlation function of galaxies.

The method implemented in TabCorr has first been described in earlier work, particularly Neistein et al. (2011) and Zheng & Guo (2016). In Lange et al. (2019a), we developed a generalized framework for this method that also takes into account assembly bias. Finally, a good reference for the TabCorr code itself is Lange et al. (2019b).
