camb (conda): Code for Anisotropies in the Microwave Background by Antony Lewis and Anthony Challinor  Features:   - Support for closed, open and flat models   - Scalar, vector and tensor modes including polarization   - Output Cl, matter transfer functions, matter power spectrum and σ8   - Fast computation to ~0.3-0.1% accuracy, with controllable accuracy level   - Relatively structured and easily extendable Fortran 90 code   - Efficient support for massive neutrinos   - Absolute computations from correctly normalized initial power spectra   - Computation of lensed CMB power spectra and lensing potential power spectrum   - Internally parallelized for fast execution on multi-processor machines   - Use CAMB with CosmoMC for Monte-Carlo parameter estimation   - Constant equation of state quintessence (or variable PPF)   - Support for general correlated adiabatic/isocurvature initial conditions   - Accurate full-sky calculation of lensed power spectra (astro-ph/0502425)   - Integrated interface to HALOFIT for non-linear fitting   - support for arbitrary neutrino mass splittings   - For 21cm, lensing and number count power spectra see this extension   - For perturbed recombination and effect on small-scale baryons see this extension   - Calculation of local primordial and CMB lensing bispectra   - Easy-to-use Python wrapper
