What's new
- Supplemental code to compute the redshift-space cross power spectrum (based on TNS model) is added (SPTcorr_cross_power.tgz). This has been used in the eBOSS (DR16) paper (2020/07/17)
- Supplemental package for redshift-space power spectrum is added. See RegPT page (2017/12/04)
- Python package RESPRESSO is released (2017/08/31)

Codes and packages
RESPRESSO
RESPRESSO is the Python package developed by T. Nishimichi, F. Bernardeau, A. Taruya. The package gives you the predictions of nonlinear matter power spectrum based on a novel method with response function. Download link is here.
RegPT
RegPT is fortran package for fast power spectrum calculations at two-loop order. Click here for download.
Matter power spectrum in real space
- Standard PT (1-loop) :
stdPTreal.f
- Standard PT (2-loop) :
You need Monte Carlo integrator and PT kernel generator:
- Monte Carlo integrator:
- PT kernel generator: kernel_PT.f
- Lagrangian PT (1-loop) :
LPTreal.f
- Closure theory :
CLAreal.tgz (f77),
CLAreal_f90.tgz
(f90, MPI implimentation)
(you further need a library file, libcuba.a,
which can be created from
Cuba library )
In addition to the above file, a common read file for output data is needed :
read_pk_real.f
Matter power spectrum in redshift space
- Standard PT (1-loop) :
stdPTred.f
- Lagrangian PT (1-loop) :
LPTred.f
- Improved prescription for redshift-space power spectrum based on
TNS model :
