Maps of the observed Brγ (LIRGs) and Paα (ULIRGs) emission. The angular scale of each object is indicated by a white horizontal bar that marks 1 arcsec. The nucleus of each object (defined as the brightest region in the K-band continuum, see Paper I) is labeled as “N”, whereas the remaining regions are tagged as “R#” by decreasing total observed flux (see Table B.1). The white (grey) ellipses over each individual region are the 1σ fitting to the 2D Gaussian profile, whereas the white (grey) dashed circles have r_eff radius. The colour scheme is logarithmic and autoscaled.
