Notes. The temperatures are given in keV. The column density is 1.46 × 10²¹ cm⁻². The normalization of the CXB model components are listed Table C.1.

^(a)

Defined as in units of cm⁻⁵, where D_A is the angular distance and n_e, n_H represent the electron and hydrogen density.

^(b)

The emission measure Y ≡ n_en_HV in units of 10⁶⁴ m⁻³.

^(c)

The electron temperature of the hot model is set to 5 × 10⁻⁴ keV to mimic the absorption of a neutral plasma.
