The results of a spectral analysis of the perseus observation, focusing on the cool and warm portions of the data. The analysis includes figures and tables presenting the best-fit redshifts, hydrogen column densities (nh), and temperatures (kt) for both portions of the data, along with their uncertainties. The document also includes notes on the fitting process.

Figure 1: Spectral analysis of cool portion of the Perseus observation in the 5.0-8.0 keV energy band. The best-fit redshift and 1 σ and 90% uncertainties are z=0.0164, (0.0142-0.0173) and (0.0116-0.0179). This gives ∆z =0.15%, ∆z 1 σ =0.06%, and ∆z90% =0.0%
Figure 2: Spectral analysis of warm portion of the Perseus observation in the 5.0-8.0 keV energy band. The best-fit redshift and 1 σ and 90% uncertainties are z=0.0132, (0.0096-0.0152) and (0.0092-0.0167). This gives ∆z =0.47%, ∆z 1 σ =0.27%, and ∆z90% =0.12%
