A 2-D regularized least square inversion code for solar rotation has been constructed which approximates the rotation rate by piecewise polynomials projected on B-splines. It is applied to the rotational splitting data of BBSO (Ref. 1). A discussion of the influence of the number and order of the spline basis on the results is given. Preliminary results of inversion with LOI data (Ref. 2) are presented.
Key words:inverse problem, solar rotation.
