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.

Name Δα Δδ v α v δ

S43 −0.488 −0.126 +215 +310
S79 0.647 −0.532 +44 +52
S90 0.533 0.969 +33 +20
S50 −0.507 0.519 −114 +380

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.
