$^{\star}$ 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).
