CLUMPY v3: gamma-ray and neutrino signals from dark matter at all scales

We present the third release of the CLUMPY code for calculating gamma-ray and neutrino signals from annihilations or decays in dark matter structures. This version includes the mean extragalactic signal with several pre-defined options and keywords related to cosmological parameters, mass functions for the dark matter structures, and gamma-ray absorption up to high redshift. For more flexibility and consistency, dark matter masses and concentration are now defined with respect to a user-defined overdensity Delta. We have also made changes for the user’s benefit: distribution and versioning of the code via git, less dependencies and a simplified installation, better handling of options in run command lines, consistent naming of parameters, and a new Sphinx documentation at http://lpsc.in2p3.fr/clumpy/.
