On the Temporal Changes of Helioseismic Properties Derived with Different Techniques
Abstract
I present a detailed comparison of the temporal changes of the characteristics of the low and intermediate p-modes oscillations derived from nearly 20 years of observations acquired from three instruments (GONG, MDI and HMI) and computed using three quite different data reduction pipe-lines. The comparisons are both at the level of mode characteristics (frequency, linewidth, amplitude and asymmetry) and at the level of inferred properties of the solar interior (i.e., changes in the solar internal rotation).
