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 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
uncertainty of the
zero point,
,
is not included in this column and
has to be taken into account when considering absolute
photometry. (f) Magnitude in the NACO
band filter. (g) Uncertainty in
.
For more information see
also footnote e. The 1
uncertainty of the
zero point is

(h) Magnitude in the NACO L' band filter. (i) Uncertainty in L'. For more information see
also footnote e. The 1
uncertainty of the
zero point is
.
(j) A value of 0.0 in the table indicates that
the corresponding measurement is not available.
