Abstract

The quiescent X-ray emission shows a power-law tail up to 18 keV. We show that an interpretation in terms of free-free emission by non-thermal particles requires unrealistic large values for the number of particles involved and for the energy input required to maintain the population. The data can however be satisfactorily explained by a differential emission measure distribution indicating the presence of substantial amounts of plasma with temperatures of 108 K.
