Notes.  (a) Distance from Sgr A* projected on the sky. (b) Offset in right ascension from Sgr A*. Uncertainties in the astrometric positions can be as large as $\sim$0.1'' because high precision astrometry was not at the focus of this work. The conversion to offsets from Sgr A* was done by assuming a pixel scale of 0.027'' per pixel (ESO NACO manual). The camera rotation angle was assumed 0 deg east of north and no camera distortion solution was applied. (c) Offset in declination from Sgr A*. For more information see also footnoteb. (d) Magnitude in the NACO H band filter. (e) Uncertainty in H, obtained by quadratically combining the formal uncertainty from PSF fitting, based on Gaussian read-out noise and Poisson photon noise, and the uncertainty due to the limited knowledge of the PSF. The 1$\sigma$ uncertainty of the zero point, $\Delta ZP_{H}=0.06$, is not included in this column and has to be taken into account when considering absolute photometry. (f) Magnitude in the NACO $K{\rm s}$ band filter. (g) Uncertainty in $K{\rm s}$. For more information see also footnote e. The 1$\sigma$ uncertainty of the zero point is $\Delta ZP_{K{\rm s}}=0.06$. (h) Magnitude in the NACO L' band filter. (i) Uncertainty in L'. For more information see also footnote e. The 1$\sigma$ uncertainty of the zero point is $\Delta ZP_{L'}=0.15$. (j) A value of 0.0 in the table indicates that the corresponding measurement is not available.
