We developed an IDL widget interface (MPF Widget) to model planetary systems using combined astrometric and radial velocity data. MPF Widget drives a Levenberg-Marquardt fitting algorithm to simultaneously fit data for parallax, proper motion and up to seven planets. This visualization tool is helpful for locating good initial guesses that allow the Levenberg-Marquardt fitting algorithm to converge on the global minimum chi squared value. It also includes tools for periodogram analysis and the capability to fit planets sequentially working with the residual data from each preceding model. MPF Widget was developed to test simulated data for the Space Interferometry Mission (SIM) and would be a useful tool for teaching the effects of each Keplerian parameter on observational data. We thank NASA and SIM for supporting this project.
