Lutz and Kelker found that surveys tend to this infer this quantity at about 30 percent less than what it truly is. The fifth root of 100 is a defining ratio for a system used to measure this quantity, the Pogson scale. The tendency to select objects with a high value for this quantity is known as the Malmquist bias. Pieter van Rhijn and Jacobus Kapteyn made a ";curve"; plotting distributions of this quantity, which Edwin Salpeter used to posit a ";formation function"; that would connect functions of this quantity to the IMF. This quantity is analogously defined for a galaxy as the Schechter f

This quantity is analogously defined for a galaxy as the Schechter function. The maximum value for this quantity is proportional to mass, since a star's radiation pressure needs to overcome gravity; that bound on this quantity is the Eddington Limit. The vertical axis of an HR diagram plots, for 10 points, what quantity, the amount of energy emitted from a body, such as a star?
