Spectra of four regions: in the western shell inside 30 Dor (upper left), close to the centre of 30 Dor (upper right), in the western part of the non-thermal shell of 30 Dor C (lower left), and a region between SN 1987A and SNR N132D with no bright structure in Hα emission (lower right). Spectra of all TMs are shown in different colours. The thin dashed lines indicate the spectral components of the astrophysical background spectrum. The straight line shows the particle background. The source components are highlighted with thick lines (dotted: lower-temperature vapec1; dashed: higher-temperature vapec2; dash-dotted: powerlaw).
