Top panel: GIRAFFE/MEDUSA regular grid overlaid on an optical Digital Sky Survey image of 30 Dor. The spatial separation between each fiber corresponds to 20′′ (~5 pc). Middle panel: MEDUSA irregular grid. Bottom panel: MEDUSA stellar grid (VFTS survey). The field-of-view on the sky shown in the lower two panels is larger than in the top panel to show all the fibers available. The red rectangle in the middle panel indicates the region covered by the regular grid.
