Pairs of panels for the five targets observed with OSIRIS/GTC. In the left panel of each set, we show an 1′× 1′ spatial view of the target in Sloan r′ band. North is up, east is left. The slit in each case is shown with solid lines and targets are indicated with blue arrows. In the right panel of each set, we show the respective two-dimensional portion of the GTC spectrum of the object, centered on the Hα line. We particularly emphasize star 2 (large set of panels) and indicate the candidate LBV/YHG B324, located ~30″ away.
