We provide MCMC chains in CosmoMC format (.txt, .paramnames, .ranges files)
The tarball kids2dflenschains.tar.gz contains the chains for the fiducial and conservative analysis cases in Joudaki et al. (2018). 
Note that the chains contain the pre-burn phase. In order to remove the burn-in phase of the MCMC the first 30% of the lines should not be considered. 
The chains are provided in the "_N.txt" ascii files, with N = 1..8. They contain a total of 63 primary and derived parameters for the MCMC samples, as well as ln(Likelihood x prior) and χ2 values. Please note that the amplitude of likelihood x prior is neglected. The chains are obtained from CosmoMC and are compatible with its plotting utility, GetDist.
The format of each line in these files is as follows:
Column 1: weight of the point
Column 2: -ln(Likelihood x prior)
Columns 3-65: a list of 63 primary and derived parameters (and χ2) as specified in the ".paramnames" files and the prior ranges are given in the ".ranges" files.
Note that it is important to propagate the weight of each point in the calculation of posterior probability distributions!
