Left: combined XMM-Newton EPIC image of 30 Dor C in false colour with red, green, and blue corresponding to 0.3–1 keV, 1–2 keV, and 2–7 keV. Also shown is the region to the north of 30 Dor C which highlights the highly variable background in the region. The image has been exposure-corrected in each energy band and have the QPB subtracted and binned into 2 × 2 pixel bins before being adaptively smoothed using the XMM-ESAS task adapt-2000. The position of Source 6, which is discussed as a possible compact object in Sect. 4.2.1, is also marked. Right: same as left but with the spectral analysis regions indicated. See Sect. 3.3.1 for a description of the regions.
