Simulated spectrum from a 1Ms observation of the center of our cluster toy model (black line) and its best fit (red line). This spectrum is extracted from the central bin of the circular binning shown in the summary table in Fig. 1. An inset figure shows the details of the lines observed around 1 keV. The lower panel shows the error in units of χ for each bin. The quantized shape observed at the highest energies comes from the low number counts observed at these high energies.
