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
