Vicinity of the black hole up to 10′′ from Sgr A*. Red points with errors represent the observed profile, and are connected by continuous line. The black long-dashed line is the normalized PSF. Two models convolved with PSF are also presented: green dotted line for keV, and blue short-dashed line for keV. Residuals are shown for the best fitted model in the range up to 10′′, i.e. for keV.
