Orbits of ED-3 stars and NGC 3201 integrated for 0.5 Gyrs forwards and backwards. Two ED-3 stars are shown with different colours to illustrate the difference in the orbital phase of the stars in v_z<0 stream (e.g. ED-3-3089 in red) and the v_z > 0 stream (e.g. ED-3-2449 in blue). The shaded region around NGC 3201’s orbit is 100 samples from the observables within the errors. For NGC 3201 this shading corresponds to a longer integration of 1.5 Gyrs to show how after several revolutions the orbits match the ED-3 stars. Brown points show the Gjöll stream from Gaia EDR3 STREAMFIDNER (Ibata et al. 2021), which overlaps with the trailing part of the orbit of NGC 3201. The arrows in the bottom corner of each panel show the direction of the velocity vector for NGC 3201, ED-3-3089 and ED-3-2449 in green, red and blue respectively.
