A new code for Fourier-Legendre analysis of large datasets: first results and a comparison with ring-diagram analysis
H. -P. Doerr, M. Roth, A. Zaatri +2
Fourier-Legendre decomposition (FLD) of solar Doppler imaging data is a promising method to estimate the sub-surface solar meridional flow. FLD is sensible to low-degree oscillatio…

Comparison of the sidereal angular velocity of subphotospheric layers and small bright coronal structures during the declining phase of solar cycle 23
Amel Zaatri, Hubertus Woehl, Markus Roth +2
Context. We compare solar differential rotation of subphotospheric layers derived from local helioseismology analysis of GONG++ dopplergrams and the one derived from tracing small…
