GRB hosts observed with FLAMES. Top row: imaging of the field, the position of the GRB is marked by a green cross, the FLAMES FOV is shown by a red rectangle. Images are from HST for GRB 020903, GRB 030329, GRB 060218 and GRB 100316D (Fruchter et al. 2006; Svensson et al. 2010). For GRB 050826 we used data from the PanSTARRS survey, for GRB 031203 imaging from FORS 2/VLT from the ESO archive. Second row: Hα maps interpolated to ∼0.02″ for better visualization with contours overplotted using the broad-band image in the top row. Third and fourth row: velocity and dispersion maps of the sample derived from a single Gaussian fit to Hα. The maps are interpolated to the resolution of the image used for the contour plot (0.02″ for the ones with HST imaging, 0.25″ for the FORS and PanSTARRS images of the hosts of GRB 031203 and GRB 050826). The nominal resolution including the seeing is shown by a circle for each host. In all plots north is up and east is left.
