globular cluster luminosity function

(distribution of brightness of globular clusters)

The globular cluster luminosity function (GCLF) is an observed density function of the occurrence of globular clusters at various B-band absolute magnitudes. The distribution peaks at about absolute magnitude -6.5. This is taken as a distance indicator for galaxies: by assembling a histogram of globular clusters in a galaxy by apparent magnitude, the absolute magnitude, and thus the distance of some of them can be inferred.
