    <subfield code="a">&lt;p&gt;This dataset contains the processed source data used to generate Figs. 4 and 5 in the article &amp;ldquo;Experimental Evidence for Jump Rope Vortices in Turbulent Convective Superstructures&amp;rdquo; published in Physical Review Fluids.&lt;/p&gt;

&lt;p&gt;The dataset includes:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Dimensionless horizontal wavelength data (&lt;span class="math-tex"&gt;\(\lambda\)&lt;/span&gt;/H) as a function of the Rayleigh number (Ra) used in Fig. 4.&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;Dimensionless oscillation frequency data (fH&amp;sup2;/&lt;span class="math-tex"&gt;\(\kappa\)&lt;/span&gt;) as a function of the Rayleigh number used in Fig. 5.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;Corresponding uncertainty estimates for the experimentally obtained quantities.&lt;/p&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The data were extracted from ultrasonic Doppler velocimetry (UDV) measurements performed in a liquid-metal Rayleigh&amp;ndash;B&amp;eacute;nard convection experiment with aspect ratio &lt;span class="math-tex"&gt;\(\Gamma
\)&lt;/span&gt;&amp;nbsp;= 25 and Prandtl number Pr &lt;span class="math-tex"&gt;\(\approx\)&lt;/span&gt; 0.03.&lt;/p&gt;

&lt;p&gt;Only processed data required for reproducing the published figures are included in this repository.&lt;/p&gt;</subfield>
