The Systemic Console Package

The Systemic Console is a software package for the fitting of Doppler radial velocity (RV) and transit timing observations arising from arbitrarily complex planetary systems. To illustrate its capabilities, we analyze a new RV dataset and synthetic datasets for the HD128311 planetary system and show that integrated fits that combine radial velocities and a small number of transit timing observations in a self-consistent fashion can greatly constrain the orbital parameters of a perturbing body.
