Inverted rotation results for KIC 7341231  with three synthetic rotation profiles: a solid body (top panel), a step function (middle panel), and a smooth function (bottom panel), each shown with a thick black line. The results from an RLS inversion (red), an OLA inversion (dark blue) and functional fitting of a step function (light blue) are shown in solid lines, with the uncertainty shown with dashed lines. The uncertainties make it difficult to distinguish a difference in the inversion results for the different synthetic profiles, although the inversion results exclude the solid body case and correctly retrieve the sign of the gradient in the bottom two panels.
