Properties of the priors set in the MCMC analysis for the background parameters.

Parameter Shape Central value Width
CRPB norm. (MOS) Gaussian Best Fit of mos-back spectra 2% intrinsic scatter
CRPB norm. (pn) Gaussian Best fit of pn-back spectra renormalized by Eq. (2) 6% intrinsic scatter
RFC norm. (MOS) Uniform inFOV–outFOV, with Eq. (A.1) Intrinsic scatter
RFC norm. (pn) Uniform inFOVPN and outFOVMOS2 with Eqs. (A.1) and (A.2) Intrinsic scatter
LHB norm. Gaussian Best fit in background region 1σ errors
GH temp. Gaussian Best fit in background region 1σ errors
GH norm. Gaussian Best fit in background region 1σ errors
CXB norm. Gaussian Best fit in background region 1σ errors

Notes. For each of them, we report the shape of the prior, how we computed its central value, and its width.
