The number of spaxels in each radial bin shown in Figure 2, with the isolated SBs (top) and post-merger galaxies (bottom) shown separately to account for the significant increase in spaxel count in the isolated SB comparison sample. The least populated radial bin is always R < 0.1R_e as expected; larger radial bins will contain more spaxels than inner bins. Beyond R = 1R_e, the quality cuts we employ to select high S/N star-forming spaxels result in less spaxels contributing (given Hα S/N falls off with radius).
