Table A.3

H-band positions and proper motion velocities for the S-source presented by Gillessen et al. (2009) calculated for the epoch 2006.5 and assuming that 1 mas/year corresponds to 40 km s^-1 at the distance of the Galactic center.

Notes. Following the information given by Gillessen et al. (2009), the typical uncertainties are ± 1 mas for the positions and ± 6 km s^-1 for the velocities. For other S-sources used in the modeling presented in Fig. A.1, see Table 6.
