Example IRAC SEDs overlaid with a series of template galaxies: TDG‐N (pink line), Elliptical (Silva et al. 1998; green line), S0 (Devriendt et al. 1999; red line), M82 nuclear region (Lutz et al. 1998; dark blue line), and an I Zw 1 (Weedman et al. 2005; light blue line). Sources with the suffix "a" are outside the projected H I ring. TDG‐N is source 26, and TDG‐S is source 33. Source 42 is an example of a good match to TDG‐N, i.e., a candidate TDG; source 13 is a reasonable match to TDG‐N and is characterized as a star‐forming region; source 48a is a "notched" SED, indicating star formation; the Seashell (source 35) matches both the elliptical and S0 templates; NGC 5291 (source 44) matches the S0 template; and source 12a is a power law, characteristic of an AGN.
