$^{\star}$ Model components as available in XSPEC: PHABS represents the Galactic foreground absorption, VPHABS the absorption
in the LMC~with reduced metal abundances, VRAYMOND and VMEKAL emission from hot plasma in collisional ionization 
equilibrium with variable abundances and VNEI emission from a non-equilibrium plasma (see also Sect.~3).
