Orbits and data of G1, G2, and G2t, fit under the constraint that they share the same orbital plane, semimajor axis, and eccentricity. Top: on-sky appearance of the two orbits. Middle: radial velocities. Bottom: spatial coordinates as a function of time. The non-Keplerian shapes result from the drag force acting on G2 and G2t when they are close to Sgr A*.
