Orbits if the Berkeley 29 and Saurer 1 clusters from EDR3 data. Left: location of Saurer 1 and Berkeley 29 in Galactic coordinates. The white symbols are the Sagittarius stream particles modelled by Law & Majewski (2010). The arrows indicate mean tangential velocities corrected for the solar motion (V_ℓ, V_b). The background is the integrated extinction model of Green et al. (2015), beyond 2 kpc. Right: integrated orbits of Saurer 1 and Berkeley 29. The Sun’s position and Galactic centre are indicated as the usual Sun’s symbol and cross, respectively.We find that the orbits of these clusters are very similar and typical of the disc.
