Table 2.
Best-fit values for the temperature, density, Fe, Si, S, Mg, Ca, and Ar abundances, and the Ar/Fe ratio (for the narrow band analysis, the Fe abundance is taken from the broad-band fit), and their associated uncertainties (quoted at the 68.27% or 1σ level) obtained from the various spectral fitting and deprojection methods employed in the paper.
