\subsection{Real data: ET70}  \textit{if new shape has a better convergence (see comments)}: I have run \textbf{shape} with the new fitting routine on the asteroid 2000 ET70. ET70 has had its shape fit in the past, using \textbf{shape} and the SPF fitting routine (reference shantanu). \textbf{shape} with SRIF has converged on a lower $\chi^2$. as indicated in figure ?  \par  \textit{if new shape has a worse convergence}: I have run \textbf{shape} with the new fitting routine on the asteroid 2000 ET70. \textbf{shape} was run initially with an ellipsoid model. The starting conditions for the this model were such that the ellipsoid axes were all equal (Figure ?a). The best fit ellipsoid model (Figure ?b) was then converted into a spherical harmonics model with 200 model components. This spherical harmonic model was then fit as well (Figure ?c). The initial ellipsoid model fit resulted in a $\chi^2$ drop of $34\%$. The spherical harmonic fit resulted in a $\chi^2$ drop of $13\%$. Figure ? (not yet generated)  indicates the surface gravity field for ET70 given the final shape. Table ? (not yet generated)  gives the moments of inertia for ET70 given the final shape. \par (the above was a clunky paragraph)
