Abstract
ROOD and Ulrich1 have discussed the oblateness of solar models with a rotating core. They find a larger oblateness for the same model than we did2. We have looked again into the oblateness calculation and now believe that the correct solution of the equations of Goldreich and Schubert3 gives an oblateness for the final model of our2 sequence C4 in agreement with the value derived by Rood and Ulrich. We also agree with Rood and Ulrich's explanation for the discrepancy.
