ZeldovichRecon computes the halo correlation function using the Zeldovich approximation. It includes 3 variants:
- zelrecon.cpp, which computes the various contributions to the correlation function;
- zelrecon_ctypes.cpp, which is designed to be called from Python using the ctypes library; and
- a version which implements the "ZEFT" formalism of "A Lagrangian effective field theory" [arxiv:1506.05264] including the alpha term described in that paper.
