  "abstract": "The analysis of flare start-times confirms the periods found years ago (Aschenbach et al., 2004) in the near-infrared and X-ray light-curves related to the Sgr A* black hole. The assignment of the frequencies found to radial and vertical epicyclic frequencies $\\nu\\sb{\\rm r}$, $\\nu\\sb{\\rm v}$, respectively, as well as to the Kepler orbital frequency $\\nu\\sb{\\rm K}$ reveals resonances of $\\nu\\sb{\\rm v}$ / $\\nu\\sb{\\rm r}$=7:2, and $\\nu\\sb{\\rm K}$ / $\\nu\\sb{\\rm v}$=3:1. The highest observed frequency of 10 mHz is identified as the Kepler frequency corrected by the rotational frame-dragging frequency, as expected from the Lense-Thirring effect. These frequency assignments conclude a black hole mass of M = (4.10-4.34)$\\times10\\sp{6} M_\\odot$ and a spin of a = (0.99473-0.99561).",
