Left images: Fe Kα maps centred at the position of the G0.24–0.17 filament during the 2000–2001 and 2012 XMM-Newton observations. The maps are in units of ph cm⁻² s⁻¹ pixel⁻¹, with 2.5^″ pixel size, and smoothed using a Gaussian kernel of 8 pixels in radius. Centre: Mopra CS(1–0) map integrated over the 27–35 km s⁻¹ velocity band. Right: Fe Kα light curve of the G0.24–0.17 filament. The blue band indicates the level of background emission measured in a circular region south of Sgr A^⋆. All errors shown on the light curves are 1σ errors (68% confidence level).
