  "abstract": "<p><strong>IPTA DR2 common red noise, MCMC output</strong><br>\n&nbsp;</p>\n\n<p>These files are the primary output from a Markov chain Monte Carlo (MCMC) sampling process. They are samples from the posterior probability distribution for a particular model described in the companion paper.</p>\n\n<p>Each zipped tarball contains four files.&nbsp; The &quot;chain&quot; file has several tab-separated columns, each of which corresponds to a model parameter, except the last four which are metadata. &nbsp;The parameter names (including metadata)&nbsp;are listed in the companion &quot;params&quot; file.&nbsp; The frequencies used in the common red noise models are listed in the &quot;crn_frequencies&quot; file.&nbsp; Additional information is provided in a README file.</p>\n\n<p>Each row of the chain file&nbsp;is one sample from the model posterior. &nbsp;The first samples at the beginning of the MCMC are the &quot;burn-in&quot; phase, before the chain has converged to the posterior. &nbsp;We recommend discarding the first ~25% of samples before using them to make inferences.</p>",
