Radial-velocity estimates for the peak Hα and [N II]emission (left- and right-hand panels, respectively) in the vicinity of R136 at the centre of the MUSE mosaic. Contours mark the most prominent X-ray sources from Chandra 1.1–2.3 KeV imaging (Townsley et al. 2006a,b), with the strongest sources labelled in the left-hand panel. Velocities are plotted on the same scale as in Fig. 10. The average PSF of the MUSE data (≈1″) is indicated in the right-hand panel by the green dot in the south-eastern corner.
