A combination of inverse and forward analysis techniques has been applied to p-modes rotational splittings in order to infer the solar rotation rate in the deeper radiative regions (r < 0.45Rodot). In this analysis, we first infer the rotation distribution down to 0.45Rodot using a 2D inversion method. We then use that rotation rate to discuss the compatibility of different low degree splittings sets. These low degree splittings and the 2D inversion method are also used to infer the rotation rate in the deeper radiative regions (r < 0.45Rodot). An exhaustive analysis of the averaging kernels has been carried out in order to study the resolution and precision of the solution.
