Descripción
Accurate determination of the rotation rate in the inner radiative zone
(0.2 < r/Rsolar < 0.5) of the sun from helioseismic
observations requires rotational frequency splittings of exceptional
quality. Indeed, only low degree modes are sensitive to the dynamics of
the deep interior. Low and intermediate degree splittings have been
estimated from a variety of instruments as well as different data
analysis procedures. It is therefore not surprising that these
determinations present significant differences. We present a study of
the three more common data sets used to infer the solar rotation rate,
namely LOWL, GONG and SOI/MDI. Our purpose is to find the common
features present in the three sets, in order to build a robust
determination of the rotation rate in the solar interior. We also have
analyzed the effect of using rotational splittings estimated by fitting
an asymmetric profile rather than a symmetric Lorentzian as a model for
the limit spectrum.
