$\begin{figure} \par\includegraphics[width=7cm,angle=90,clip]{9699fig2.ps} \end{figure}$ Figure 2: Upper panel: radial temperature profile of RXC J2228.6+2036. Diamonds: the deprojected temperature and the solid line is the best-fit profile. Stars: for the PSF-corrected temperature (see Sect. 5.1). We offset the stars 5'' to the left so as to illustrate these two kinds of temperature clearly. Bottom panel: radial deprojected abundance of RXC J2228.6+2036. The confidence level is 90%.

In b) we plot the isothermal and the cooling flow components, and the lower lines below the crosses represent the multiphase components of pn (bold line) and MOS (faint lines), which show that the multiphase components provide only a small contribution to the emission.
