Public Hα image of 30Dor taken with the Wide Field Imager on the 2.2 m telescope of La Silla. The dots and crosses show the positions of the three families of profiles discussed in the text, color-coded as follows: blue for blueshifted single profiles; red redshifted single profiles; yellow crosses double profiles; and cyan dots multiple profiles. The red and blue dots with white rims have radial velocities close to zero (|V | < 2.5 km s⁻¹). The lower-right corner (SW) of the image portrays the slow expanding shell of the supernova remnant 30DorB. The scale shown in the lower-left corner corresponds to 15 pc.
