Image of Clump2E in Hα (log scale) is shown in the upper-left panel. The two brightest H II regions, with more than one nebular line detected, are marked with blue diamonds in a zoom in image of the Hα emission in the upper-right panel (linear scale). The Hα smoothed contour levels at 1.2, 2, 4, 10, 20 × 10⁻²⁰ erg s⁻¹ cm⁻² per pixel shape a partial ring of radius ∼0.6 kpc. They are marked also on the VLT red continuum image (bottom-left panel) and on the FUV-GALEX image (bottom-right panel). The blue crosses, at the location of the Hα sources listed in Table 3, are some examples of the marginally detected faint Hα emitters with no optical counterpart.
