The E+NE region uses the geometric midpoint of the E and NE pointings as its center. ^cRange of effective length scale, including the uncertainties characterized by the emissivity fraction range of 40 − 60% (see Sect. 4.3 and Appendix A.3). ^dICM temperature. ^eFe abundance relative to the lpgs proto-solar abundances (Lodders et al. 2009), see Fig. A.1. ^fICM redshift. ^gBulk velocity of the ICM in the rest frame of the central ICM (z_icm = 0.017628) with heliocentric correction. ^hICM velocity dispersion. For reference, the sound speed of 5 − 6 keV gas is ≃1100 − 1250 km s⁻¹. ⁱNonthermal pressure fraction (see Sect. 4.1). ^jCombined fit of the E and NE pointings.
