  <dc:description>This dataset contains the processed source data used to generate Figs. 4 and 5 in the article “Experimental Evidence for Jump Rope Vortices in Turbulent Convective Superstructures” published in Physical Review Fluids.

The dataset includes:


	Dimensionless horizontal wavelength data (\(\lambda\)/H) as a function of the Rayleigh number (Ra) used in Fig. 4.
	
	Dimensionless oscillation frequency data (fH²/\(\kappa\)) as a function of the Rayleigh number used in Fig. 5.
	
	
	Corresponding uncertainty estimates for the experimentally obtained quantities.
	


The data were extracted from ultrasonic Doppler velocimetry (UDV) measurements performed in a liquid-metal Rayleigh–Bénard convection experiment with aspect ratio \(\Gamma
\) = 25 and Prandtl number Pr \(\approx\) 0.03.

Only processed data required for reproducing the published figures are included in this repository.</dc:description>
