Left: Fe Kα map centred at the position of Sgr D during the 2012 XMM-Newton observations. The map is in units of ph cm ⁻² s⁻¹ pixel⁻¹, with 2.5^″ pixel size, and smoothed using a Gaussian kernel of 15 pixels radius. The region labelled Sgr D includes the bulk of the Fe Kα emission in the complex. Middle: CS map integrated in the velocity range 50 to 70 km s⁻¹ showing the molecular counterpart of the 6.4 keV emission. Right: Fe Kα light curve of the Sgr D complex integrating over the region indicated on the maps. The blue band indicates the level of background emission. All errors shown on the light curves are 1σ errors (68% confidence level).
