Notes. Columns 1–3 represent the galaxy name and distance and an indicative inclination. Columns 4–5 give the integrated 3.6 μm luminosity of the disk and bulge (if present). Column 6 gives the stellar half-light radius. Comments on the quality and data references are given in Cols. 7, 8.

Reference. (1) Little THINGS (Iorio et al. 2017); (2) Little THINGS (Oh et al. 2015); (3) SPARC (Lelli et al. 2016); (4) THINGS (de Blok et al. 2008); (5) Corbelli et al. (2014). Comments: (a) potential starburst; (b) uncertain inclination for outer disk; (c) extended bar; and (d) poorly constrained distance. * For M33 Col. 4 gives the stellar mass from Corbelli et al. (2014) (in M) instead of the 3.6 μm luminosity.
