Cosmological Parameters Estimations the clean way
CAMEL is a high quality software for performing Cosmological Parameters Estimations with current and future data. Written from scratch in pure C++, emphasis was put in building a clean and carefully-designed project that can grow harmoniously with time. The software was largely tested/debugged and used intensively in these articles. It uses by default the CLASS software to compute all relevant cosmological quantities, but any other Boltzmann solver can easily be plugged in. For instance PICO (fast interpolation between pre-computed CMB spectra) is also available.

CAMEL incorporates all the latest cosmological likelihoods and gives access to several parameter estimation methods through the same parameter file:

  • High quality Maximum Likelihood Estimate (using Minuit), aka "best fits"
  • Profile likelihoods
  • Markov Chain Monte Carlo (MCMC) with an adaptive scheme for faster convergence (or when you don't know a-priori your proposal)

Note that you don't need any C++ skills to use CAMEL (and very little to add you own data)
The code is distributed on GitLab : CAMEL GitLab
