Almost all galaxy properties correlate with each other to some degree; in this bounty of agreement, how are we to extract essentials? Fortunately, there is a framework in which to interpret CO correlations. Empirical studies have indicated that the fundamental galaxy properties are scale and form (Whitmore 1984), and theoretical work has implied that this follows from the physics of galaxy formation (see Lin and Pringle 1987, and references therein). It is known that the CO luminosity of galaxies is a function of both their scale (Young and Scoville 1982) and their form (Verter 1987). But the interpretation of any individual correlation is shrouded by uncertainties in the conversion from observables to source population properties.
