Diagnostics of the underlying physical differences between flocculent and well-defined spiral galaxies
From published catalogs, basic physical properties including diameters, masses, and neutral hydrogen contents of spiral galaxies have been studied as a function of the arm class. The results indicate that galaxies with well-defined arms have longer scale-lengths (a difference comparable in the red to that in the blue) and are more massive (in both
