Cheat-sheet for all available interfaces in Corrfunc

This guide assumes that you already followed the Package Installation section of the documentation to get the package and its dependencies set up on your machine. There are three available interfaces in Corrfunc

Calculating spatial clustering statistics in simulation boxes

Corrfunc can compute a range of spatial correlation functions and the counts-in-cells. The easiest way to get help on the command-line is by calling the executables without any input parameters. Here is the list of executables associated with each type of clustering statistic:

Clustering Statistic Python Interface Static library Command-line (executable name)
\(\xi(r)\) Corrfunc.theory.DD theory/DD/libcountpairs.a theory/DD/DD
\(\xi(r_p,\pi)\) Corrfunc.theory.DDrppi theory/DDrppi/libcountpairs_rp_pi.a theory/DDrppi/DDrppi
\(w_p(r_p)\) Corrfunc.theory.wp theory/wp/libcountpairs_wp.a theory/wp/wp
\(\xi(r)\) Corrfunc.theory.xi theory/xi/libcountpairs_xi.a theory/xi/xi
\(pN(n)\) Corrfunc.theory.vpf theory/vpf/libcountspheres.a theory/vpf/vpf

Calculating clustering statistics in mock catalogs

The list of clustering statistics supported on mock catalogs and the associated command-line executables are:

Clustering Statistic Python Interface Static library Command-line (executable name)
\(\xi(r_p,\pi)\) Corrfunc.mocks.DDrppi_mocks mocks/DDrppi_mocks/libcountpairs_rp_pi_mocks.a mocks/DDrppi_mocks/DDrppi_mocks
\(\omega(\theta)\) Corrfunc.mocks.DDtheta_mocks mocks/DDtheta_mocks/libcountpairs_theta_mocks.a mocks/DDtheta_mocks/DDtheta_mocks
\(pN(n)\) Corrfunc.mocks.vpf_mocks mocks/vpf_mocks/libcountspheres_mocks mocks/vpf_mocks/vpf_mocks
