Reconstructed image of UM 462 made by simulating the action of a broad filter in the I band with contours showing the ‘leaves’ and ‘branches’ according to the hierarchical clustering provided by astrodendro. Besides, several polygons in dashed lines mark the location of structures within the galaxy of particular interest in terms of ionisation or kinematics. A map in Hα flux made by line fitting on a spaxel-by-spaxel basis is overplotted with ten evenly spaced contours (in logarithmic scale) ranging from 1.26 × 10⁻¹⁸ erg cm⁻² s⁻¹ spaxel⁻¹ to 1.26 × 10⁻¹⁵ erg cm⁻² s⁻¹ spaxel⁻¹.
