Spatial distribution of the presumably single O-type stars as a function of LC. North is to the top; east is to the left. The circles define regions within 2.4 of NGC 2070 (central circle) and NGC 2060 (south-west circle). Different symbols indicate LC: III (circles), II (squares), I (triangles). Note that because of crowding a considerable fraction of the sources overlap. Lower opacities again denote sources with an ambiguous LC classification, similar as in Fig. 1.
