For 2 decades, surveys for giant planets have produced the acquisition data of various kind (via transits, direct imaging (DI) or radial velocity technic (RV)). Also, some stars have been observed several times using at least one detection method. The final purpose of these surveys (RV and DI) is to better understand the formation of giant planets (GPs) at short and long separations, for different stellar spectral type, and various initial conditions. Statistical studies are then primordial to bring constraints on the planetary formation scenarios. Combining all the available data (RV and/or DI) represents a more robust approach to bring these constraints since it considers the overall available data. Multi Epoch Multi-purpose Exoplanet Simulation System (MESS2, an advanced version of MESS (Bonavita et al. 2012)) is a powerful statistical tool used for multiple epochs of DI and RV observations. It is a Monte Carlo code based on Bayesian methods.
