Best fit and 3σ confidence range of a possible additional flux added by a Gaussian line at 3.55 keV.


Mixing-angle limits (3σ confidence) for the 7.1 keV sterile neutrino decay scenario (negative mixing-angle unphysical results from allowing negative flux).


Weighted average properties of the cluster sample weighting contributions as described in Eq. (2) in Sect. 6.2.
