CFASTPT

C version of FAST-PT -- Xiao Fang

The official python version of FAST-PT is hosted at https://github.com/JoeMcEwen/FAST-PT.

Our papers (JCAP 2016, 9, 15; arXiv:1603.04826) and (JCAP 2017, 2, 30; arXiv:1609.05978) describe the FAST-PT algorithm and implementation. Please cite these papers when using FAST-PT in your research.

For the nonlinear galaxy bias implementation, cite JCAP 2016, 9, 15 (arXiv:1603.04826).

For the intrinsic alignment implementation, cite JCAP 2017, 2, 30 (arXiv:1609.05978) and PRD, 100, 103506 (arXiv:1708.09247).

Available Modules:

nonlinear galaxy bias terms: Pd1d2, Pd2d2, Pd1s2, Pd2s2, Ps2s2, Pd1d3nl
nonlinear (tidal alignment & tidal torquing) intrinsic galaxy alignment terms: IA_tt, IA_ta, IA_mix
