ModeCode numerically solves the perturbation equations and resulting spectrum for arbitrary inflationary potentials and implements Bayesian parameter estimation for inflation. ModeCode was derived from code previously used in Peiris et al. (2003) and Mortonson, Dvorkin, Peiris & Hu (2009) which was based on the algorithm developed in Adams, Cresswell and Easther (2001).
In 2014, ModeCode was generalised to deal with multifield scenarios and interfaced with PolyChord. The new version, MultiModeCode, was described in Price, Frazer, Xu, Peiris and Easther (2014).
ModeCode is no longer actively supported.
