The Code for Anisotropies in the Microwave Background [CAMB] is a Fortran 90 application that computes cosmic microwave background (CMB) spectra given a set of input cosmological parameters. The package was written by Antony Lewis and Anthony Challinor and may be downloaded from http://camb.info/. It is based on CMBFAST by U. Seljak and M. Zaldarriaga.
