Welcome to Nbody n-point function documentation

This set of modules helps exploiting the simulated data available through the skies and universes data base http://projects.ift.uam-csic.es/skies-universes/

It currently hosts parts of the N body simulation: MultiDark and its projections into mock catalogs for emission line galaxies and quasars.


If you use this code as a ressource to produce a scientific result, please :
  • cite the paper Comparat et al. 2017 https://arxiv.org/abs/1702.01628
  • and acknowledge the skies and universes database as follows : “The skies and universes database is hosted by the UAM/CSIC-IFT cloud and funded by the Spanish MICINNs Consolider-Ingenio 2010 Programme, the MultiDark CSD2009-00064 grant and the MINECO Centro de Excelencia Severo Ochoa Programme under the grants SEV-2012-0249, FPA2012-34694, and the projects AYA2014-60641-C2-1-P and AYA2012-31101.”


requirements :
  • python 2.7.8 and its main packages all installable through pip: numpy, scipy, matplotlib, math ...
  • astro dependencies: astropy, pyneb, icrar hmf package. All are also installable with pip

git clone https://github.com/JohanComparat/nbody-npt-functions.git

Add all the python folders you can list them like this: ls $NBODY_NPT_DIR/*/python) to your pythonpath.

in the folder multidark,
  • bin_DF : scripts related to density field analysis
  • bin_MD : scripts transforming MultiDark database catalogs into lighter versions to work with
  • bin_onePT : scripts to compute 1-point functions
  • bin_twoPT : scripts to compute 2-point functions
