    <description descriptionType="Abstract">&lt;p&gt;&lt;strong&gt;IPTA DR2 common red noise, MCMC output&lt;/strong&gt;&lt;br&gt;
&amp;nbsp;&lt;/p&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;Each zipped tarball contains four files.&amp;nbsp; The &amp;quot;chain&amp;quot; file has several tab-separated columns, each of which corresponds to a model parameter, except the last four which are metadata. &amp;nbsp;The parameter names (including metadata)&amp;nbsp;are listed in the companion &amp;quot;params&amp;quot; file.&amp;nbsp; The frequencies used in the common red noise models are listed in the &amp;quot;crn_frequencies&amp;quot; file.&amp;nbsp; Additional information is provided in a README file.&lt;/p&gt;

&lt;p&gt;Each row of the chain file&amp;nbsp;is one sample from the model posterior. &amp;nbsp;The first samples at the beginning of the MCMC are the &amp;quot;burn-in&amp;quot; phase, before the chain has converged to the posterior. &amp;nbsp;We recommend discarding the first ~25% of samples before using them to make inferences.&lt;/p&gt;</description>
