Complementary data used in this work for NGC 2146. GALEX FUV, Spitzer MIPS, Herschel SPIRE and PACS, radio, and CO(2−1) maps are presented. The optical image in the Red filter displays the optical features of this galaxy and is not used in the analysis. The Planck 1.38 mm and radio 6.2 cm maps are also not shown due to poor resolution. All the demonstrated maps have the same FoV of 3.5′×4′, centered on the galaxy. The maps are displayed in logarithmic scale and their original resolution (see indicated Table 2); the beam size is represented by a white circle in the bottom left corner of each map.
