This folder contains all the MCMC chains used for the paper. As MCMC chains, the point density reflects the posterior probability.

They have *not* had burnin removed. The paper burned 1/3 of the chain.

These chains were created using cosmosis and sampled with emcee using 50 walkers (Goodman and Weare algorithm). That means that the samples are not uncorrelated. To create a “Metropolis-Hastings”-like uncorrelated chain, the chain must be “flattened”. See the emcee documentation.

After appropriate flattening, the chains pass the Dunkley et al 2005 convergence test after burn in.

As cosmosis chains, they have a header describing the settings.

The Boltzmann code used was axionCAMB, modified for isocurvature initial conditions.

These chains were created by Renée Hlozek with help of David J. E. Marsh.
