The Chandra ACIS 0.4–2 keV spectrum of ESO 286-IG19, fitted with a thermal emission spectrum (MEKAL) with a solar abundance pattern (left) and that of the core-collapse SNe (right), in which O viii (0.65 keV), Ne ix (1.0 keV), Mg xi (1.36 keV) and Si xiii (1.85 keV) are more pronounced. The χ² values for the two fits are 53 and 37 for 41 and 40 degrees of freedom, respectively.
