Misleading variations in estimated rotational frequency splittings of solar p modes: consequences for helioseismology and asteroseismology
The aim of this paper is to investigate whether there are any 11-yr or quasi-biennial solar-cycle-related variations in solar rotational splitting frequencies of low-degree solar p modes. Although no 11-yr signals were observed, variations on a shorter time-scale (˜2 yr) were apparent. We show that the variations arose from complications/artefacts
