Notes. Comparison of our measured proper motions and those from the SDSS database as used by P14 (Cols. 2–5). Galactic rest-frame velocities in Cols. 6 and 7 are based on our proper motions νGRF,1 or SDSS proper motions νGRF,2. The present height above the Galactic plane is denoted with z. The quantities r and rmin give the average and shortest distance to the GC at the 3σ level of the disk passage using new proper motions and model II of Irrgang et al. (2010). The last three columns give the bound probabilities as listed by P14 (Col. 11), our results based on model II, and the proper motions from SDSS as given in Cols. 4 and 5 (Col. 12) and based on our revised proper motions from Cols. 2 and 3 in the last column.
