Period, color, and luminosity for cepheid variables.
Abstract
The Cepheids of the galaxy and the Magellanic clouds display a graduation in properties, but when amplitude as well as period is taken into account, their intrinsic colors are sensibly similar. The period luminosity relations in the three systems are probably parallel, but not necessarily coincident.
