Notes.

^(a)

The adopted inner and outer radii for the annular spectrum extraction region for EPIC−ACIS comparison.

^(b)

The β-profile parameters are obtained in this work, except that for Coma we adopted the values from Briel et al. (1992)

^(c)

Estimated using the formula in Vikhlinin et al. (2006).

^(d)

The contribution from outside the isothermal region (r > 0.3 r₅₀₀) to the projected extraction region.

^(e)

The fraction of the emission within r_in and r_out due to the PSF scatter from the central cool region in pn.
