Observed intensity maps (not reddening-corrected). First row: continuum emission between 4500 and 4700 Å (a spectral region free from gas emission). Rows 2 to 5: emission-line flux maps derived from Gaussian fits to each line and spaxel (see text for details). Axis units are arcseconds; north is up, east to the left. All images are shown in logarithmic scale. Flux units are 10^-18 erg cm^-2 s^-1. Spaxels where the blue Wolf-Rayet bump is visible are marked by stars in the [O iii] map.
