Emission line and continuum maps. From left to right and top to bottom: Maps of the observed Hα and [OIII]λ5007 Å emission line fluxes (in units of 10⁻²⁰ erg/s/cm² and in logarithmic scale); A_V extinction (in magnitudes); observed continuum fluxes in the blue and red parts of the spectrum (5400 Å and 8150 Å, respectively; in units of 10⁻¹⁷ erg/s/cm² and in logarithmic scale); and EW (Hα) in Å. The top and bottom left and centre images show superimposed the contours of the HST-UV image described in the text. Orientation is north up, east to the left.
