Slit positions, field of view (FOV) and approximate aperture positions for Haro 11 (left) and ESO 338-IG04 (right), overlayed on HST/ACS F550M continuum images (i.e. close in wavelength to the Na D feature). The X-shooter slits are 0.9 (or 1.0 for the UVB-arm, not marked in the figure) arcsec wide and 11 arcsec long and marked with solid lines. The FOV for the LR6 setting (which includes Hα) is marked with dash-dotted lines while the shorter LR5 setting (including Na D) is marked with dotted lines. The Argus binned “apertures” are 1.56 arcsec wide squares marked with dashed lines. The VLT/FLAMES FOV shown here shows the area for which we have full exposure after taking into account the dithering.
