Precession rates for bodies at different distances from the star for a disk-density profile index p = 1. The four analytical values , , and are compared to the numerical values. Even if F^BT has values close to the stars that are different from F^W and F^SR because of the lack of an inner cutoff, when used to compute the precession rate, its predictions are indistinguishable from those of the other two approaches (W and SR).
