Lensing effects affecting a portion of the S2 orbit (dashed blue line) and the E0 orbit (solid black). These simulated shifts in the astrometric observations are obtained considering a Keplerian model taking into account the lensing effects. This effect is added by using the analytical formulas developed in Sereno & de Luca (2006).
