    <subfield code="a">&lt;p&gt;This material is part of several data products associated with GWTC-3, the third Gravitational-Wave Transient Catalog from the &lt;a href="https://www.ligo.org/"&gt;LIGO&lt;/a&gt; Scientific Collaboration, the &lt;a href="https://www.virgo-gw.eu/"&gt;Virgo&lt;/a&gt; Collaboration, and the &lt;a href="https://gwcenter.icrr.u-tokyo.ac.jp/en/"&gt;KAGRA&lt;/a&gt; Collaboration. For more information, see the paper (&lt;a href="https://dcc.ligo.org/LIGO-P2000318/public"&gt;dcc.ligo.org/LIGO-P2000318/public&lt;/a&gt;), the related material linked from this page, and the GWTC-3 data release documentation (&lt;a href="https://www.gw-openscience.org/GWTC-3/"&gt;www.gw-openscience.org/GWTC-3/&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Candidate data release&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Data associated with candidates in GWTC-3. These are gravitational-wave candidates from the&amp;nbsp;the third observing run (O3) of the Advanced LIGO and Advanced Virgo detectors that pass a false alarm rate threshold of 2/day. We upload a tar file (search_data.tar.gz) containing all the data and a python notebook (GWTC3_search_data.ipynb) that provides a description on how to use the files contained in the dataset.&lt;/p&gt;

&lt;p&gt;Associated with each candidate are the search analysis results and a localization (assuming that the source is astrophysical). Four search analysis pipelines have been used: the templated-based &lt;a href="https://lscsoft.docs.ligo.org/gstlal/"&gt;GstLAL&lt;/a&gt;, &lt;a href="https://doi.org/10.1088/1361-6382/abe913"&gt;MBTA&lt;/a&gt; and &lt;a href="https://pycbc.org/"&gt;PyCBC&lt;/a&gt;, plus the template-free &lt;a href="https://gwburst.gitlab.io/"&gt;cWB&lt;/a&gt;. Localizations from the template-based pipelines are calculated using &lt;a href="https://lscsoft.docs.ligo.org/ligo.skymap/bayestar/index.html"&gt;Bayestar&lt;/a&gt;, while cWB candidates are calculated by cWB itself.&lt;/p&gt;

&lt;p&gt;This release is primarily composed of results from the second part of O3 (O3b), but also includes a subset of results&amp;nbsp;from the first part (O3a). A similar release was made for the previous &lt;a href="https://doi.org/10.5281/zenodo.5117761"&gt;GWTC-2.1&lt;/a&gt;&amp;nbsp;that&amp;nbsp;contained candidates from the first part of O3 (O3a)&amp;nbsp;from GstLAL, MBTA and PyCBC. We include updated probabilities of astrophysical origin for these candidates: each search analysis has a o3a_pastro directory that contains these results. Since GWTC-2.1 did not include cWB results, this release includes cWB O3a candidates in addition to O3b:&amp;nbsp;the cWB directory contains a subdirectory called o3a_events that contains the O3a results.&lt;/p&gt;

&lt;p&gt;The probability of astrophysical origin is calculated assuming a compact binary coalescence source, which may not always be appropriate for&amp;nbsp;the template-free cWB analysis.&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&amp;nbsp;&lt;/p&gt;
