Spectral fitting models and parameters.

Components	XSPEC
	Model	kT	Norm ^(a)
ICM	tbabsapec*	–	–
LHB	apec	9.25 × 10⁻²	6.88 × 10⁻⁴
GH	tbabsapec*	0.198	1.37 × 10⁻³

	Model	Γ	Norm ^(b)
CXB (R1)	tbabspow*	1.52	1.05 × 10⁻³
CXB (R2&R3)	tbabspow*	1.40	7.57 × 10⁻⁴

Notes. Temperatures are given in keV. The column density is 1.74 × 10²⁰ cm⁻².

^(a)

Normalisation of apec model 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 two different CXB normalisations used for the different rounds of analysis. The unit is photons keV⁻¹ cm⁻² s⁻¹ at 1 keV. All normalizations are calculated assuming uniform emission from a circular region with a radius of 20 arcmin.
