Data related to "Horizontal velocity eigenfunctions of solar inertial modes using local correlation tracking of magnetic features"

This dataset contains horizontal-velocity eigenfunctions of solar inertial modes, generated using the LCT pipeline behind Joshi, N., Liang, Z.-C., Fournier, D., et al., "Horizontal velocity eigenfunctions of solar inertial modes using local correlation tracking of magnetic features" (Astronomy & Astrophysics, accepted, 2026). Each eigenfunction gives u_phi and u_theta versus latitude (73 points, -90 to 90 degrees), cleaned via Legendre-polynomial projection with 1-sigma Monte Carlo error bars. rossby_eigenfunctions holds modes extracted over the full 2010-2024 span plus sliding time windows to track solar-cycle variation. paper_eigenfunctions holds five modes extracted independently by three methods — LCT on magnetic-feature tracking, LCT on granulation tracking, and ring-diagram analysis — for direct comparison.
