Verification of the helioseismic Fourier-Legendre analysis for meridional flow measurements

Verification of the helioseismic Fourier-Legendre analysis for meridional flow measurements

Measuring the Sun's internal meridional flow is one of the key issues of helioseismology. Using the Fourier-Legendre analysis is a technique for addressing this problem. We validate this technique with the help of artificial helioseismic data. The analysed data set was obtained by numerically simulating the effect of the meridional …
