The individual luminosity functions are well fitted by Schechter functions with alpha = -1.25. The composite luminosity function of all 14 clusters is best fitted by a Schechter function with alpha = -1.21 and a characteristic magnitude of -20.02 in B(J) (H0 = 100 km/s). It is found that there is no variation of cluster luminosity functions with richness of Bautz-Morgan type. The composite luminosity function of high velocity dispersion clusters has a fainter magnitude than that of the low velocity dispersion clusters.2993717 bytesapplication/pdfen-AUgalactic clustersluminous intensityastronomical photometrydynamic characteristics1989
