Background-subtracted Chandra spectra in the vicinity of G0.13−0.11. The colors correspond to the regions shown in Fig. 3 and are identified in this figure. The solid lines show the best-fitting absorbed power-law model fits to these spectra. While a pure power law can describe the compact source spectrum (blue) reasonably well, other regions clearly contain a non-negligible contribution of thermal emission that gives rise to emission lines at low energies. The spectrum of the intermediate polar CXOUGC J174622.7−285218 is shown in purple.
