Notes. Column 1: inner and outer radius in arcsec; column 2: inner and outer radius in kiloparsecs ; column 3: deprojected temperature (kiloelectron volts); column 4: abundance (solar fraction); column 5: electron density (centimeter⁻³); column 6: pressure (10⁻¹¹ erg centimeter⁻³); column 7: entropy (kiloelectron volts centimeter²); column 8: integrated gas mass (10¹³ solar masses). The global fit gives χ²/dof= 1972.7/1920 = 1.027.
