Zoom in to the central region of NGC 5253 showing all the available IFU data on the location of the WR star population. Within GMOS IFU positions 1, 2 and 3, the red WR bump flux is represented with white contours. The size of the seeing disk for positions 1 and 2 () is shown in the top left. The large white dashed rectangle shows the VLT/FLAMES-ARGUS IFU position of Monreal-Ibero et al. (2010), and the labelled cyan and magenta rectangles show the regions in which evidence for a blue WR bump and He ii emission was found, respectively.
