(a) Galactic Center region of 5 × 5 arcsec as seen by NACO at 2.2 micron. The central white box indicates the region shown in panel b. (b) Image of GC region of 0.8 × 0.8 arcsec from the GRAVITY acquisition camera in H-band. The central white box indicates the region shown in panel c. (c) Image of central 240 × 240 mas region with Sgr A* deconvolved with the CLEAN algorithm and overlaid on the residual background. The dashed circles in both panels b and c indicate the GRAVITY fiber FOV with a HWHM of ∼74 mas. S2 was outside of this region and its flux was reduced by fiber damping by about a factor of 100.
